So I'm trying to create a batch file to run a PowerShell script while bypassing the execution policy. Oddly, it worked a single time, but without me editing anything, it will not run again. I've created other files thinking maybe my file somehow got corrupted, but nothing... Any chance someone sees anything blatantly wrong with this?
#echo off
Powershell.exe -Command "& {Start-Process Powershell.exe -ArgumentList '-ExecutionPolicy Bypass -File %~dp0File.ps1' -Verb RunAs}"
PAUSE
The *.ps1 file works by itself if I click through the prompts. Also, if I manually set the execution policy in PowerShell to Bypass, this batch file still does not work. This is not a process I usually need to take, so I'm curious if anyone sees anything wrong with how this is written?
If this is just to run your script, what I personally do is create a shortcut of the script and then modify the Target of the shortcut:
Target: Powershell.exe -ExecutionPolicy Bypass -File "C:\scriptpath\script.ps1"
If you want your script to be executed as Administrator you can add this to the top of the main script:
$myInvoke="-file `"$($MyInvocation.ScriptName)`""
Start-Process "$PSHome\powershell.exe" -Verb Runas -ArgumentList $myInvoke -EA 'Stop'
If the shortcut will always be in the same folder as your script you can also leave Start In blank and change the path for Powershell.exe -ExecutionPolicy Bypass -File ".\script.ps1" by doing so if you copy the entire folder to a different location, the shortcut will still work.
You know how if you're the administrative user of a system and you can just right click say, a batch script and run it as Administrator without entering the administrator password?
I'm wondering how to do this with a PowerShell script. I do not want to have to enter my password; I just want to mimic the right-click Run As Administrator method.
Everything I read so far requires you to supply the administrator password.
If the current console is not elevated and the operation you're trying to do requires elevated privileges then you can start powershell with the Run as Administrator option :
PS> Start-Process powershell -Verb runAs
Microsoft Docs: Start-Process
Here is an addition to Shay Levi's suggestion (just add these lines at the beginning of a script):
if (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{
$arguments = "& '" +$myinvocation.mycommand.definition + "'"
Start-Process powershell -Verb runAs -ArgumentList $arguments
Break
}
This results in the current script being passed to a new powershell process in Administrator mode (if current User has access to Administrator mode and the script is not launched as Administrator).
Self elevating PowerShell script
Windows 8.1 / PowerShell 4.0 +
One line :)
if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process powershell.exe "-NoProfile -ExecutionPolicy Bypass -File `"$PSCommandPath`"" -Verb RunAs; exit }
# Your script here
Benjamin Armstrong posted an excellent article about self-elevating PowerShell scripts. There a few minor issue with his code; a modified version based on fixes suggested in the comment is below.
Basically it gets the identity associated with the current process, checks whether it is an administrator, and if it isn't, creates a new PowerShell process with administrator privileges and terminates the old process.
# Get the ID and security principal of the current user account
$myWindowsID = [System.Security.Principal.WindowsIdentity]::GetCurrent();
$myWindowsPrincipal = New-Object System.Security.Principal.WindowsPrincipal($myWindowsID);
# Get the security principal for the administrator role
$adminRole = [System.Security.Principal.WindowsBuiltInRole]::Administrator;
# Check to see if we are currently running as an administrator
if ($myWindowsPrincipal.IsInRole($adminRole))
{
# We are running as an administrator, so change the title and background colour to indicate this
$Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)";
$Host.UI.RawUI.BackgroundColor = "DarkBlue";
Clear-Host;
}
else {
# We are not running as an administrator, so relaunch as administrator
# Create a new process object that starts PowerShell
$newProcess = New-Object System.Diagnostics.ProcessStartInfo "PowerShell";
# Specify the current script path and name as a parameter with added scope and support for scripts with spaces in it's path
$newProcess.Arguments = "& '" + $script:MyInvocation.MyCommand.Path + "'"
# Indicate that the process should be elevated
$newProcess.Verb = "runas";
# Start the new process
[System.Diagnostics.Process]::Start($newProcess);
# Exit from the current, unelevated, process
Exit;
}
# Run your code that needs to be elevated here...
Write-Host -NoNewLine "Press any key to continue...";
$null = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown");
Here's a self-elevating snippet for Powershell scripts which preserves the working directory:
if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
Start-Process PowerShell -Verb RunAs "-NoProfile -ExecutionPolicy Bypass -Command `"cd '$pwd'; & '$PSCommandPath';`"";
exit;
}
# Your script here
Preserving the working directory is important for scripts that perform path-relative operations. Almost all of the other answers do not preserve this path, which can cause unexpected errors in the rest of the script.
If you'd rather not use a self-elevating script/snippet, and instead just want an easy way to launch a script as adminstrator (eg. from the Explorer context-menu), see my other answer here: https://stackoverflow.com/a/57033941/2441655
You can create a batch file (*.bat) that runs your powershell script with administrative privileges when double-clicked. In this way, you do not need to change anything in your powershell script.To do this, create a batch file with the same name and location of your powershell script and then put the following content in it:
#echo off
set scriptFileName=%~n0
set scriptFolderPath=%~dp0
set powershellScriptFileName=%scriptFileName%.ps1
powershell -Command "Start-Process powershell \"-ExecutionPolicy Bypass -NoProfile -NoExit -Command `\"cd \`\"%scriptFolderPath%`\"; & \`\".\%powershellScriptFileName%\`\"`\"\" -Verb RunAs"
That's it!
Here is the explanation:
Assuming your powershell script is in the path C:\Temp\ScriptTest.ps1, your batch file must have the path C:\Temp\ScriptTest.bat. When someone execute this batch file, the following steps will occur:
The cmd will execute the command
powershell -Command "Start-Process powershell \"-ExecutionPolicy Bypass -NoProfile -NoExit -Command `\"cd \`\"C:\Temp\`\"; & \`\".\ScriptTest.ps1\`\"`\"\" -Verb RunAs"
A new powershell session will open and the following command will be executed:
Start-Process powershell "-ExecutionPolicy Bypass -NoProfile -NoExit -Command `"cd \`"C:\Temp\`"; & \`".\ScriptTest.ps1\`"`"" -Verb RunAs
Another new powershell session with administrative privileges will open in the system32 folder and the following arguments will be passed to it:
-ExecutionPolicy Bypass -NoProfile -NoExit -Command "cd \"C:\Temp\"; & \".\ScriptTest.ps1\""
The following command will be executed with administrative privileges:
cd "C:\Temp"; & ".\ScriptTest.ps1"
Once the script path and name arguments are double quoted, they can contain space or single quotation mark characters (').
The current folder will change from system32 to C:\Temp and the script ScriptTest.ps1 will be executed. Once the parameter -NoExit was passed, the window wont be closed, even if your powershell script throws some exception.
Using
#Requires -RunAsAdministrator
has not been stated, yet. It seems to be there only since PowerShell 4.0.
http://technet.microsoft.com/en-us/library/hh847765.aspx
When this switch parameter is added to your requires statement,
it specifies that the Windows PowerShell session in which you are
running the script must be started with elevated user rights
(Run as Administrator).
To me, this seems like a good way to go about this, but I'm not sure of the field experience, yet. PowerShell 3.0 runtimes probably ignore this, or even worse, give an error.
When the script is run as a non-administrator, the following error is given:
The script 'StackOverflow.ps1' cannot be run because it contains a
"#requires" statement for running as Administrator. The current
Windows PowerShell session is not running as Administrator. Start
Windows PowerShell by using the Run as Administrator option, and then
try running the script again.
+ CategoryInfo : PermissionDenied: (StackOverflow.ps1:String) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : ScriptRequiresElevation
You can easily add some registry entries to get a "Run as administrator" context menu for .ps1 files:
New-Item -Path "Registry::HKEY_CLASSES_ROOT\Microsoft.PowershellScript.1\Shell\runas\command" `
-Force -Name '' -Value '"c:\windows\system32\windowspowershell\v1.0\powershell.exe" -noexit "%1"'
(updated to a simpler script from #Shay)
Basically at HKCR:\Microsoft.PowershellScript.1\Shell\runas\command set the default value to invoke the script using Powershell.
The code posted by Jonathan and Shay Levy did not work for me.
Please find the working code below:
If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{
#"No Administrative rights, it will display a popup window asking user for Admin rights"
$arguments = "& '" + $myinvocation.mycommand.definition + "'"
Start-Process "$psHome\powershell.exe" -Verb runAs -ArgumentList $arguments
break
}
#"After user clicked Yes on the popup, your file will be reopened with Admin rights"
#"Put your code here"
You need to rerun the script with administrative privileges and check if the script was launched in that mode. Below I have written a script that has two functions: DoElevatedOperations and DoStandardOperations. You should place your code that requires admin rights into the first one and standard operations into the second. The IsRunAsAdmin variable is used to identify the admin mode.
My code is an simplified extract from the Microsoft script that is automatically generated when you create an app package for Windows Store apps.
param(
[switch]$IsRunAsAdmin = $false
)
# Get our script path
$ScriptPath = (Get-Variable MyInvocation).Value.MyCommand.Path
#
# Launches an elevated process running the current script to perform tasks
# that require administrative privileges. This function waits until the
# elevated process terminates.
#
function LaunchElevated
{
# Set up command line arguments to the elevated process
$RelaunchArgs = '-ExecutionPolicy Unrestricted -file "' + $ScriptPath + '" -IsRunAsAdmin'
# Launch the process and wait for it to finish
try
{
$AdminProcess = Start-Process "$PsHome\PowerShell.exe" -Verb RunAs -ArgumentList $RelaunchArgs -PassThru
}
catch
{
$Error[0] # Dump details about the last error
exit 1
}
# Wait until the elevated process terminates
while (!($AdminProcess.HasExited))
{
Start-Sleep -Seconds 2
}
}
function DoElevatedOperations
{
Write-Host "Do elevated operations"
}
function DoStandardOperations
{
Write-Host "Do standard operations"
LaunchElevated
}
#
# Main script entry point
#
if ($IsRunAsAdmin)
{
DoElevatedOperations
}
else
{
DoStandardOperations
}
Adding my 2 cents. My simple version based on net session which works all the time so far in Windows 7 / Windows 10. Why over complicate it?
if (!(net session)) {$path = "& '" + $myinvocation.mycommand.definition + "'" ; Start-Process powershell -Verb runAs -ArgumentList $path ; exit}
just add to the top of the script and it will run as administrator.
You can also force the application to open as administrator, if you have an administrator account, of course.
Locate the file, right click > properties > Shortcut > Advanced and check Run as Administrator
Then Click OK.
This behavior is by design. There are multiple layers of security since Microsoft really didn't want .ps1 files to be the latest email virus. Some people find this to be counter to the very notion of task automation, which is fair. The Vista+ security model is to "de-automate" things, thus making the user okay them.
However, I suspect if you launch powershell itself as elevated, it should be able to run batch files without requesting the password again until you close powershell.
A number of the answers here are close, but a little more work than needed.
Create a shortcut to your script and configure it to "Run as Administrator":
Create the shortcut.
Right-click shortcut and open Properties...
Edit Target from <script-path> to powershell <script-path>
Click Advanced... and enable Run as administrator
Here is how to run a elevated powershell command and collect its output form within a windows batch file in a single command(i.e not writing a ps1 powershell script).
powershell -Command 'Start-Process powershell -ArgumentList "-Command (Get-Process postgres | Select-Object Path | Select-Object -Index 0).Path | Out-File -encoding ASCII $env:TEMP\camp-postgres.tmp" -Verb RunAs'
Above you see i first launch a powershell with elevated prompt and then ask that to launch another powershell(sub shell) to run the command.
C:\Users\"username"\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Windows PowerShell is where the shortcut of PowerShell resides. It too still goes to a different location to invoke the actual 'exe' (%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe).
Since PowerShell is user-profile driven when permissions are concerned; if your username/profile has the permissions to do something then under that profile, in PowerShell you would generally be able to do it as well. That being said, it would make sense that you would alter the shortcut located under your user profile, for example, C:\Users\"username"\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Windows PowerShell.
Right-click and click properties. Click "Advanced" button under the "Shortcut" tab located right below the "Comments" text field adjacent to the right of two other buttons, "Open File Location" and "Change Icon", respectively.
Check the checkbox that reads, "Run as Administrator". Click OK, then Apply and OK. Once again right click the icon labeled 'Windows PowerShell' located in C:\Users\"username"\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Windows PowerShell and select "Pin to Start Menu/Taskbar".
Now whenever you click that icon, it will invoke the UAC for escalation. After selecting 'YES', you will notice the PowerShell console open and it will be labeled "Administrator" on the top of the screen.
To go a step further... you could right click that same icon shortcut in your profile location of Windows PowerShell and assign a keyboard shortcut that will do the exact same thing as if you clicked the recently added icon. So where it says "Shortcut Key" put in a keyboard key/button combination like: Ctrl + Alt + PP (for PowerShell). Click Apply and OK.
Now all you have to do is press that button combination you assigned and you will see UAC get invoked, and after you select 'YES' you will see a PowerShell console appear and "Administrator" displayed on the title bar.
I have found a way to do this...
Create a batch file to open your script:
#echo off
START "" "C:\Scripts\ScriptName.ps1"
Then create a shortcut, on your desktop say (right click New -> Shortcut).
Then paste this into the location:
C:\Windows\System32\runas.exe /savecred /user:*DOMAIN*\*ADMIN USERNAME* C:\Scripts\BatchFileName.bat
When first opening, you will have to enter your password once. This will then save it in the Windows credential manager.
After this you should then be able to run as administrator without having to enter a administrator username or password.
I am using the solution below. It handles stdout/stderr via transcript feature and passes exit code correctly to parent process. You need to adjust transcript path/filename.
If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{
echo "* Respawning PowerShell child process with elevated privileges"
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.FileName = "powershell"
$pinfo.Arguments = "& '" + $myinvocation.mycommand.definition + "'"
$pinfo.Verb = "RunAs"
$pinfo.RedirectStandardError = $false
$pinfo.RedirectStandardOutput = $false
$pinfo.UseShellExecute = $true
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
$p.WaitForExit()
echo "* Child process finished"
type "C:/jenkins/transcript.txt"
Remove-Item "C:/jenkins/transcript.txt"
Exit $p.ExitCode
} Else {
echo "Child process starting with admin privileges"
Start-Transcript -Path "C:/jenkins/transcript.txt"
}
# Rest of your script goes here, it will be executed with elevated privileges
Another simpler solution is that you may also right click on "C:\Windows\System32\cmd.exe" and choose "Run as Administrator" then you can run any app as administrator without providing any password.
The problem with the #pgk and #Andrew Odri's answers is when you have script parameters, specially when they are mandatory. You can solve this problem using the following approach:
The user right-clicks the .ps1 file and selects 'Run with PowerShell': ask him for the parameters through input boxes (this is a much better option than use the HelpMessage parameter attribute);
The user executes the script through the console: allow him to pass the desired parameters and let the console force him to inform the mandatory ones.
Here is how would be the code if the script had the ComputerName and Port mandatory parameters:
[CmdletBinding(DefaultParametersetName='RunWithPowerShellContextMenu')]
param (
[parameter(ParameterSetName='CallFromCommandLine')]
[switch] $CallFromCommandLine,
[parameter(Mandatory=$false, ParameterSetName='RunWithPowerShellContextMenu')]
[parameter(Mandatory=$true, ParameterSetName='CallFromCommandLine')]

I recently needed this to build an environment on ansible. I say right away - the decision is not mine, but I don’t remember where I got it. Looks like that:
powershell.exe -NoProfile -ExecutionPolicy Unrestricted -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Unrestricted -Command Get-Service -Name ssh-agent | Set-Service -StartupType Automatic' -Verb RunAs}";
This example enables ssh-agent autostart.
The required command is specified after -Command. The only problem is the launch happens on a new PS instance, but so far this is the only way that I know to execute the command as an admin without additional steps.
The most reliable way I've found is to wrap it in a self-elevating .bat file:
#echo off
NET SESSION 1>NUL 2>NUL
IF %ERRORLEVEL% EQU 0 GOTO ADMINTASKS
CD %~dp0
MSHTA "javascript: var shell = new ActiveXObject('shell.application'); shell.ShellExecute('%~nx0', '', '', 'runas', 0); close();"
EXIT
:ADMINTASKS
powershell -file "c:\users\joecoder\scripts\admin_tasks.ps1"
EXIT
The .bat checks if you're already admin and relaunches the script as Administrator if needed. It also prevents extraneous "cmd" windows from opening with the 4th parameter of ShellExecute() set to 0.
On top of Shay Levy's answer, follow the below setup (just once)
Start a PowerShell with Administrator rights.
Follow Stack Overflow question PowerShell says “execution of scripts is disabled on this system.”.
Put your .ps1 file in any of the PATH folders, for example. Windows\System32 folder
After the setup:
Press Win + R
Invoke powershell Start-Process powershell -Verb runAs <ps1_file>
You can now run everything in just one command line. The above works on Windows 8 Basic 64-bit.
I haven't seen my own way of doing it before, so, try this out. It is way easier to follow and has a much smaller footprint:
if([bool]([Security.Principal.WindowsIdentity]::GetCurrent()).Groups -notcontains "S-1-5-32-544") {
Start Powershell -ArgumentList "& '$MyInvocation.MyCommand.Path'" -Verb runas
}
Very simply, if the current Powershell session was called with administrator privileges, the Administrator Group well-known SID will show up in the Groups when you grab the current identity. Even if the account is a member of that group, the SID won't show up unless the process was invoked with elevated credentials.
Nearly all of these answers are a variation on Microsoft's Ben Armstrong's immensely popular method of how to accomplish it while not really grasping what it is actually doing and how else to emulate the same routine.
To append the output of the command to a text filename which includes the current date you can do something like this:
$winupdfile = 'Windows-Update-' + $(get-date -f MM-dd-yyyy) + '.txt'
if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process powershell.exe "-NoProfile -ExecutionPolicy Bypass -Command `"Get-WUInstall -AcceptAll | Out-File $env:USERPROFILE\$winupdfile -Append`"" -Verb RunAs; exit } else { Start-Process powershell.exe "-NoProfile -ExecutionPolicy Bypass -Command `"Get-WUInstall -AcceptAll | Out-File $env:USERPROFILE\$winupdfile -Append`""; exit }
This is a clarification ...
The powershell RUNAS / SAVECRED credential "is not safe", tried it and it adds the admin identity and password into the credential cache and can be used elsewhere OOPS!. If you have done this I suggest you check and remove the entry.
Review your program or code because the Microsoft policy is you cannot have mixed user and admin code in the same code blob without the UAC (the entry point) to execute the program as admin. This would be sudo (same thing) on Linux.
The UAC has 3 types, dont'see, a prompt or an entry point generated in the manifest of the program. It does not elevate the program so if there is no UAC and it needs admin it will fail. The UAC though as an administrator requirement is good, it prevents code execution without authentication and prevents the mixed codes scenario executing at user level.
Elevated PowerShell from Start>Run
You cannot run elevated powershell from the "run" command, in 2012R2 or 2016, without shelling twice:
C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell -Command "saps PowerShell -Verb RunAs "
It turns out it was too easy. All you have to do is run a cmd as administrator. Then type explorer.exe and hit enter. That opens up Windows Explorer.
Now right click on your PowerShell script that you want to run, choose "run with PowerShell" which will launch it in PowerShell in administrator mode.
It may ask you to enable the policy to run, type Y and hit enter. Now the script will run in PowerShell as administrator. In case it runs all red, that means your policy didn't take affect yet. Then try again and it should work fine.
I'm using a simple script to run another script as admin that will need to change the location of files in areas that are otherwise restricted. I've tried literally every method I could find on stackoverflow for running a script as administrator to no avail.
My 'admin' version of powershell closes instantly when I call it from another script. All I want is to be able to run a script that has adminitrative rights without the thing closing on me instantly when I gave it a script to execute.
Start-Process powershell -Verb runAs
start-process powershell -argument "C:\Scripts\Backup.ps1 TestBackup" -Verb runAs
and the next 6 answers on this page:
PowerShell: Running a command as Administrator
I expected to be able to run the passed script as admin, but instead admin powershell pops up and instantly closes.
I've had issues with relaunching a script as admin, due to execution policy, so I ended up encoding the command and running it that way:
$Code = ". 'C:\Scripts\Backup.ps1' TestBackup"
$Encoded = [Convert]::ToBase64String([Text.Encoding]::Unicode.GetBytes($code))
# Indicate that the process should be elevated
Start-Process PowerShell.exe -Verb RunAs -ArgumentList "-EncodedCommand",$Encoded
I need to run a PowerShell script from another PowerShell script as different user and hidden window.
What do I have so far:
Start-Process powershell '& C:\test.ps1' -WindowStyle Hidden -Credential $cred
where $cred is a PSCredential object. The test.ps1 script is for testing purposes one line with Remove-Item. As I can still see the file not being removed I can tell that the script is not being run.
EDIT
My original intention is to run regedit script but when I was implementing Start-Job answer (below) I've got this error:
Start-Job : The value of the FilePath parameter must be a Windows PowerShell script file. Enter th
e path to a file with a .ps1 file name extension and try the command again.
You could use jobs for this. As the Powershell documentation says
A Windows PowerShell background job runs a command without interacting
with the current session.
PS> $myJob = Start-Job -FilePath C:\test.ps1 -Credential $cred
To get the result/output of the job, use Receive-Job
PS> $myJob | Receive-Job -Keep
You can run the PowerShell scripts through task scheduler. I'm not sure if it is your goal, but it will let you execute PowerShell scripts on a user's session using their credentials.
I'll let you Google the how to, to fit your needs.
You know how if you're the administrative user of a system and you can just right click say, a batch script and run it as Administrator without entering the administrator password?
I'm wondering how to do this with a PowerShell script. I do not want to have to enter my password; I just want to mimic the right-click Run As Administrator method.
Everything I read so far requires you to supply the administrator password.
If the current console is not elevated and the operation you're trying to do requires elevated privileges then you can start powershell with the Run as Administrator option :
PS> Start-Process powershell -Verb runAs
Microsoft Docs: Start-Process
Here is an addition to Shay Levi's suggestion (just add these lines at the beginning of a script):
if (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{
$arguments = "& '" +$myinvocation.mycommand.definition + "'"
Start-Process powershell -Verb runAs -ArgumentList $arguments
Break
}
This results in the current script being passed to a new powershell process in Administrator mode (if current User has access to Administrator mode and the script is not launched as Administrator).

Here's a self-elevating snippet for Powershell scripts which preserves the working directory:
if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
Start-Process PowerShell -Verb RunAs "-NoProfile -ExecutionPolicy Bypass -Command `"cd '$pwd'; & '$PSCommandPath';`"";
exit;
}
# Your script here
Preserving the working directory is important for scripts that perform path-relative operations. Almost all of the other answers do not preserve this path, which can cause unexpected errors in the rest of the script.
If you'd rather not use a self-elevating script/snippet, and instead just want an easy way to launch a script as adminstrator (eg. from the Explorer context-menu), see my other answer here: https://stackoverflow.com/a/57033941/2441655
You can create a batch file (*.bat) that runs your powershell script with administrative privileges when double-clicked. In this way, you do not need to change anything in your powershell script.To do this, create a batch file with the same name and location of your powershell script and then put the following content in it:
#echo off
set scriptFileName=%~n0
set scriptFolderPath=%~dp0
set powershellScriptFileName=%scriptFileName%.ps1
powershell -Command "Start-Process powershell \"-ExecutionPolicy Bypass -NoProfile -NoExit -Command `\"cd \`\"%scriptFolderPath%`\"; & \`\".\%powershellScriptFileName%\`\"`\"\" -Verb RunAs"
That's it!
Here is the explanation:
Assuming your powershell script is in the path C:\Temp\ScriptTest.ps1, your batch file must have the path C:\Temp\ScriptTest.bat. When someone execute this batch file, the following steps will occur:
The cmd will execute the command
powershell -Command "Start-Process powershell \"-ExecutionPolicy Bypass -NoProfile -NoExit -Command `\"cd \`\"C:\Temp\`\"; & \`\".\ScriptTest.ps1\`\"`\"\" -Verb RunAs"
A new powershell session will open and the following command will be executed:
Start-Process powershell "-ExecutionPolicy Bypass -NoProfile -NoExit -Command `"cd \`"C:\Temp\`"; & \`".\ScriptTest.ps1\`"`"" -Verb RunAs
Another new powershell session with administrative privileges will open in the system32 folder and the following arguments will be passed to it:
-ExecutionPolicy Bypass -NoProfile -NoExit -Command "cd \"C:\Temp\"; & \".\ScriptTest.ps1\""
The following command will be executed with administrative privileges:
cd "C:\Temp"; & ".\ScriptTest.ps1"
Once the script path and name arguments are double quoted, they can contain space or single quotation mark characters (').
The current folder will change from system32 to C:\Temp and the script ScriptTest.ps1 will be executed. Once the parameter -NoExit was passed, the window wont be closed, even if your powershell script throws some exception.
Using
#Requires -RunAsAdministrator
has not been stated, yet. It seems to be there only since PowerShell 4.0.
http://technet.microsoft.com/en-us/library/hh847765.aspx
When this switch parameter is added to your requires statement,
it specifies that the Windows PowerShell session in which you are
running the script must be started with elevated user rights
(Run as Administrator).
To me, this seems like a good way to go about this, but I'm not sure of the field experience, yet. PowerShell 3.0 runtimes probably ignore this, or even worse, give an error.
When the script is run as a non-administrator, the following error is given:
The script 'StackOverflow.ps1' cannot be run because it contains a
"#requires" statement for running as Administrator. The current
Windows PowerShell session is not running as Administrator. Start
Windows PowerShell by using the Run as Administrator option, and then
try running the script again.
+ CategoryInfo : PermissionDenied: (StackOverflow.ps1:String) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : ScriptRequiresElevation
You can easily add some registry entries to get a "Run as administrator" context menu for .ps1 files:
New-Item -Path "Registry::HKEY_CLASSES_ROOT\Microsoft.PowershellScript.1\Shell\runas\command" `
-Force -Name '' -Value '"c:\windows\system32\windowspowershell\v1.0\powershell.exe" -noexit "%1"'
(updated to a simpler script from #Shay)
Basically at HKCR:\Microsoft.PowershellScript.1\Shell\runas\command set the default value to invoke the script using Powershell.
The code posted by Jonathan and Shay Levy did not work for me.
Please find the working code below:
If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{
#"No Administrative rights, it will display a popup window asking user for Admin rights"
$arguments = "& '" + $myinvocation.mycommand.definition + "'"
Start-Process "$psHome\powershell.exe" -Verb runAs -ArgumentList $arguments
break
}
#"After user clicked Yes on the popup, your file will be reopened with Admin rights"
#"Put your code here"
You need to rerun the script with administrative privileges and check if the script was launched in that mode. Below I have written a script that has two functions: DoElevatedOperations and DoStandardOperations. You should place your code that requires admin rights into the first one and standard operations into the second. The IsRunAsAdmin variable is used to identify the admin mode.
My code is an simplified extract from the Microsoft script that is automatically generated when you create an app package for Windows Store apps.
param(
[switch]$IsRunAsAdmin = $false
)
# Get our script path
$ScriptPath = (Get-Variable MyInvocation).Value.MyCommand.Path
#
# Launches an elevated process running the current script to perform tasks
# that require administrative privileges. This function waits until the
# elevated process terminates.
#
function LaunchElevated
{
# Set up command line arguments to the elevated process
$RelaunchArgs = '-ExecutionPolicy Unrestricted -file "' + $ScriptPath + '" -IsRunAsAdmin'
# Launch the process and wait for it to finish
try
{
$AdminProcess = Start-Process "$PsHome\PowerShell.exe" -Verb RunAs -ArgumentList $RelaunchArgs -PassThru
}
catch
{
$Error[0] # Dump details about the last error
exit 1
}
# Wait until the elevated process terminates
while (!($AdminProcess.HasExited))
{
Start-Sleep -Seconds 2
}
}
function DoElevatedOperations
{
Write-Host "Do elevated operations"
}
function DoStandardOperations
{
Write-Host "Do standard operations"
LaunchElevated
}
#
# Main script entry point
#
if ($IsRunAsAdmin)
{
DoElevatedOperations
}
else
{
DoStandardOperations
}
Adding my 2 cents. My simple version based on net session which works all the time so far in Windows 7 / Windows 10. Why over complicate it?
if (!(net session)) {$path = "& '" + $myinvocation.mycommand.definition + "'" ; Start-Process powershell -Verb runAs -ArgumentList $path ; exit}
just add to the top of the script and it will run as administrator.
You can also force the application to open as administrator, if you have an administrator account, of course.
Locate the file, right click > properties > Shortcut > Advanced and check Run as Administrator
Then Click OK.
This behavior is by design. There are multiple layers of security since Microsoft really didn't want .ps1 files to be the latest email virus. Some people find this to be counter to the very notion of task automation, which is fair. The Vista+ security model is to "de-automate" things, thus making the user okay them.
However, I suspect if you launch powershell itself as elevated, it should be able to run batch files without requesting the password again until you close powershell.
A number of the answers here are close, but a little more work than needed.
Create a shortcut to your script and configure it to "Run as Administrator":
Create the shortcut.
Right-click shortcut and open Properties...
Edit Target from <script-path> to powershell <script-path>
Click Advanced... and enable Run as administrator
Here is how to run a elevated powershell command and collect its output form within a windows batch file in a single command(i.e not writing a ps1 powershell script).
powershell -Command 'Start-Process powershell -ArgumentList "-Command (Get-Process postgres | Select-Object Path | Select-Object -Index 0).Path | Out-File -encoding ASCII $env:TEMP\camp-postgres.tmp" -Verb RunAs'
Above you see i first launch a powershell with elevated prompt and then ask that to launch another powershell(sub shell) to run the command.
C:\Users\"username"\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Windows PowerShell is where the shortcut of PowerShell resides. It too still goes to a different location to invoke the actual 'exe' (%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe).
Since PowerShell is user-profile driven when permissions are concerned; if your username/profile has the permissions to do something then under that profile, in PowerShell you would generally be able to do it as well. That being said, it would make sense that you would alter the shortcut located under your user profile, for example, C:\Users\"username"\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Windows PowerShell.
Right-click and click properties. Click "Advanced" button under the "Shortcut" tab located right below the "Comments" text field adjacent to the right of two other buttons, "Open File Location" and "Change Icon", respectively.
Check the checkbox that reads, "Run as Administrator". Click OK, then Apply and OK. Once again right click the icon labeled 'Windows PowerShell' located in C:\Users\"username"\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Windows PowerShell and select "Pin to Start Menu/Taskbar".
Now whenever you click that icon, it will invoke the UAC for escalation. After selecting 'YES', you will notice the PowerShell console open and it will be labeled "Administrator" on the top of the screen.
To go a step further... you could right click that same icon shortcut in your profile location of Windows PowerShell and assign a keyboard shortcut that will do the exact same thing as if you clicked the recently added icon. So where it says "Shortcut Key" put in a keyboard key/button combination like: Ctrl + Alt + PP (for PowerShell). Click Apply and OK.
Now all you have to do is press that button combination you assigned and you will see UAC get invoked, and after you select 'YES' you will see a PowerShell console appear and "Administrator" displayed on the title bar.
I have found a way to do this...
Create a batch file to open your script:
#echo off
START "" "C:\Scripts\ScriptName.ps1"
Then create a shortcut, on your desktop say (right click New -> Shortcut).
Then paste this into the location:
C:\Windows\System32\runas.exe /savecred /user:*DOMAIN*\*ADMIN USERNAME* C:\Scripts\BatchFileName.bat
When first opening, you will have to enter your password once. This will then save it in the Windows credential manager.
After this you should then be able to run as administrator without having to enter a administrator username or password.
I am using the solution below. It handles stdout/stderr via transcript feature and passes exit code correctly to parent process. You need to adjust transcript path/filename.
If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
{
echo "* Respawning PowerShell child process with elevated privileges"
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.FileName = "powershell"
$pinfo.Arguments = "& '" + $myinvocation.mycommand.definition + "'"
$pinfo.Verb = "RunAs"
$pinfo.RedirectStandardError = $false
$pinfo.RedirectStandardOutput = $false
$pinfo.UseShellExecute = $true
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
$p.WaitForExit()
echo "* Child process finished"
type "C:/jenkins/transcript.txt"
Remove-Item "C:/jenkins/transcript.txt"
Exit $p.ExitCode
} Else {
echo "Child process starting with admin privileges"
Start-Transcript -Path "C:/jenkins/transcript.txt"
}
# Rest of your script goes here, it will be executed with elevated privileges
Another simpler solution is that you may also right click on "C:\Windows\System32\cmd.exe" and choose "Run as Administrator" then you can run any app as administrator without providing any password.
The problem with the #pgk and #Andrew Odri's answers is when you have script parameters, specially when they are mandatory. You can solve this problem using the following approach:
The user right-clicks the .ps1 file and selects 'Run with PowerShell': ask him for the parameters through input boxes (this is a much better option than use the HelpMessage parameter attribute);
The user executes the script through the console: allow him to pass the desired parameters and let the console force him to inform the mandatory ones.
Here is how would be the code if the script had the ComputerName and Port mandatory parameters:
[CmdletBinding(DefaultParametersetName='RunWithPowerShellContextMenu')]
param (
[parameter(ParameterSetName='CallFromCommandLine')]
[switch] $CallFromCommandLine,
[parameter(Mandatory=$false, ParameterSetName='RunWithPowerShellContextMenu')]
[parameter(Mandatory=$true, ParameterSetName='CallFromCommandLine')]
[string] $ComputerName,

$encodedCommand = [Convert]::ToBase64String($scriptBytes)
# If this script is called from another one, the execution flow must wait for this script to finish.
Start-Process -FilePath 'powershell' -ArgumentList "-ExecutionPolicy Bypass -NoProfile -EncodedCommand $encodedCommand" -Verb 'RunAs' -Wait
}

I recently needed this to build an environment on ansible. I say right away - the decision is not mine, but I don’t remember where I got it. Looks like that:
powershell.exe -NoProfile -ExecutionPolicy Unrestricted -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Unrestricted -Command Get-Service -Name ssh-agent | Set-Service -StartupType Automatic' -Verb RunAs}";
This example enables ssh-agent autostart.
The required command is specified after -Command. The only problem is the launch happens on a new PS instance, but so far this is the only way that I know to execute the command as an admin without additional steps.
The most reliable way I've found is to wrap it in a self-elevating .bat file:
#echo off
NET SESSION 1>NUL 2>NUL
IF %ERRORLEVEL% EQU 0 GOTO ADMINTASKS
CD %~dp0
MSHTA "javascript: var shell = new ActiveXObject('shell.application'); shell.ShellExecute('%~nx0', '', '', 'runas', 0); close();"
EXIT
:ADMINTASKS
powershell -file "c:\users\joecoder\scripts\admin_tasks.ps1"
EXIT
The .bat checks if you're already admin and relaunches the script as Administrator if needed. It also prevents extraneous "cmd" windows from opening with the 4th parameter of ShellExecute() set to 0.
On top of Shay Levy's answer, follow the below setup (just once)
Start a PowerShell with Administrator rights.
Follow Stack Overflow question PowerShell says “execution of scripts is disabled on this system.”.
Put your .ps1 file in any of the PATH folders, for example. Windows\System32 folder
After the setup:
Press Win + R
Invoke powershell Start-Process powershell -Verb runAs <ps1_file>
You can now run everything in just one command line. The above works on Windows 8 Basic 64-bit.
I haven't seen my own way of doing it before, so, try this out. It is way easier to follow and has a much smaller footprint:
if([bool]([Security.Principal.WindowsIdentity]::GetCurrent()).Groups -notcontains "S-1-5-32-544") {
Start Powershell -ArgumentList "& '$MyInvocation.MyCommand.Path'" -Verb runas
}
Very simply, if the current Powershell session was called with administrator privileges, the Administrator Group well-known SID will show up in the Groups when you grab the current identity. Even if the account is a member of that group, the SID won't show up unless the process was invoked with elevated credentials.
Nearly all of these answers are a variation on Microsoft's Ben Armstrong's immensely popular method of how to accomplish it while not really grasping what it is actually doing and how else to emulate the same routine.
To append the output of the command to a text filename which includes the current date you can do something like this:
$winupdfile = 'Windows-Update-' + $(get-date -f MM-dd-yyyy) + '.txt'
if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process powershell.exe "-NoProfile -ExecutionPolicy Bypass -Command `"Get-WUInstall -AcceptAll | Out-File $env:USERPROFILE\$winupdfile -Append`"" -Verb RunAs; exit } else { Start-Process powershell.exe "-NoProfile -ExecutionPolicy Bypass -Command `"Get-WUInstall -AcceptAll | Out-File $env:USERPROFILE\$winupdfile -Append`""; exit }
This is a clarification ...
The powershell RUNAS / SAVECRED credential "is not safe", tried it and it adds the admin identity and password into the credential cache and can be used elsewhere OOPS!. If you have done this I suggest you check and remove the entry.
Review your program or code because the Microsoft policy is you cannot have mixed user and admin code in the same code blob without the UAC (the entry point) to execute the program as admin. This would be sudo (same thing) on Linux.
The UAC has 3 types, dont'see, a prompt or an entry point generated in the manifest of the program. It does not elevate the program so if there is no UAC and it needs admin it will fail. The UAC though as an administrator requirement is good, it prevents code execution without authentication and prevents the mixed codes scenario executing at user level.
Elevated PowerShell from Start>Run
You cannot run elevated powershell from the "run" command, in 2012R2 or 2016, without shelling twice:
C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell -Command "saps PowerShell -Verb RunAs "
It turns out it was too easy. All you have to do is run a cmd as administrator. Then type explorer.exe and hit enter. That opens up Windows Explorer.
Now right click on your PowerShell script that you want to run, choose "run with PowerShell" which will launch it in PowerShell in administrator mode.
It may ask you to enable the policy to run, type Y and hit enter. Now the script will run in PowerShell as administrator. In case it runs all red, that means your policy didn't take affect yet. Then try again and it should work fine.
