I have created a powershell script that runs with my account for others to use. In the script, it has a button that launches Windows Remote Assist. The problem is, as the script runs with my account, my name appears in the receiver end. I can include -credential but it will prompt for a login detail. Is there a way to launch it as a current user without any prompt?
I have tried to call another ps1 that processes msra /offerra but that still uses my credential.
Start-Process cmd.exe -ArgumentList "/C msra /offerra $StrComputer" -NoNewWindow
Is there a way to do it or is it even possible?
I am having below line of code which is part of my build process. Below code take SectionName and dotnet framework path for aspnet_regiis and encryption flag -pef to encrypt my web.config.
So when build happens i need to run the below code "Run as administrator" for that i used start-process with powershell and -Verb runas option. But when run this script i get a prompt in windows 10 with yes or no option.
How to avoid this.
$args="-pef '${SectionName}' '${configfilepath}'"
Start-process powershell -Verb runas "$(join-path ${frameworkPath} 'aspnet_regiis.exe') ${args}"
Though not the best option, you can have a shortcut to a script that runs the powershell script. Give that shortcut administrative permission and double click it / run it though CMD or something to have it run as administrator.
EDIT:
As suggested here:
PowerShell: Running a command as Administrator
You can add an if statement to ensure the -Verb runAs works.
So I can write a script in Powershell ISE, not save it, and it will run (F5/green arrow on the ISE). Once I save it, I get the error saying I can't run saved scripts. If I open a Powershell window in the directory the saved script exists, I can run it with
powershell -ExecutionPolicy ByPass -File script.ps1
But is there a way I can get this to work when running it via the ISE's green arrow/F5? I don't have admin access to this PC
Edit: Windows 10
Ok so I just found out you can set Execution Policy for yourself (current user) without having admin rights. So if you're coming here from google do this:
Set-ExecutionPolicy -Scope "CurrentUser" -ExecutionPolicy "RemoteSigned"
Also you can run individual script without setting Execution Policy for current user, by passing Execution Policy only for file script.
For example:
Powershell -executionpolicy RemoteSigned -File "C:\scripts\script.ps1"
Very convenient for scheduled tasks in the Windows Task Scheduler to run PowerShell commands (scripts).
That's my addition for google users
I have a PowerShell script that monitors an image folder. I need to find a way to automatically run this script after the computer starts.
I already tried the following methods, but I couldn't get it working.
Use msconfig and add the PowerShell script to startup, but I cannot find the PowerShell script on that list.
Create a shortcut and drop it to startup folder. No luck.
%SystemRoot%\SysWOW64\WindowsPowerShell\v1.0\powershell.exe -File "C:\Doc\Files\FileMonitor.ps1"
or
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -File "C:\Doc\Files\FileMonitor.ps1"
Here's my PowerShell script:
$folder = "C:\\Doc\\Files"
$dest = "C:\\Doc\\Files\\images"
$filter = "*.jpg"
$fsw = new-object System.IO.FileSystemWatcher $folder, $filter -Property #{
IncludeSubDirectories=$false
NotifyFilter = [System.IO.NotifyFilters]'FileName, LastWrite'
}
$onCreated = Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
Start-Sleep -s 10
Move-Item -Path C:\Doc\Files\*.jpg C:\Doc\Files\images
}
I also tried to add a basic task using taskschd.msc. It is still not working.
Here's what I found, and maybe that will help to debug it.
If I open up a PowerShell window and run the script there, it works. But if I run it in a command prompt,
powershell.exe -File "C:\Doc\Files\FileMonitor.ps1"
It will not work. I am not sure it's a permission problem or something else.
BTW, I have PowerShell 3.0 installed, and if I type $host.version, it will show 3 there. But my powershell.exe seems like it is still v1.0.
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe
I finally got my PowerShell script to run automatically on every startup. You will need to create two files: the first is the Powershell script (e.g. script.ps1) and the second is a .cmd file that will contain commands that will run on the command prompt (e.g. startup.cmd).
The second file is what needs to be executed when the computer starts up, and simply copy-pasting the .ps1 to the startup folder won't work, because that doesn't actually execute the script - it only opens the file with Notepad. You need to execute the .cmd which itself will execute the .ps1 using PowerShell. Ok, enough babbling and on to the steps:
Create your .ps1 script and place it in a folder. I put it on my desktop for simplicity. The path would look something like this:
%USERPROFILE%\Desktop\script.ps1
Create a .cmd file and place it in
%AppData%\Microsoft\Windows\Start Menu\Programs\Startup\startup.cmd
Doing this will execute the cmd file every time on startup. Here is a link of how to create a .cmd file if you need help.
Open the .cmd file with a text editor and enter the following lines:
PowerShell -Command "Set-ExecutionPolicy Unrestricted" >> "%TEMP%\StartupLog.txt" 2>&1
PowerShell %USERPROFILE%\Desktop\script.ps1 >> "%TEMP%\StartupLog.txt" 2>&1
This will do two things:
Set the Execution Policy of your PowerShell to Unrestricted. This is needed to run scripts or else PowerShell will not do it.
Use PowerShell to execute the .ps1 script found in the path specified.
This code is specifically for PowerShell v1.0. If you're running PowerShell v2.0 it might be a little different. In any case, check this source for the .cmd code.
Save the .cmd file
Now that you have your .ps1 and .cmd files in their respective paths and with the script for each, you are all set.
You could set it up as a Scheduled Task, and set the Task Trigger for "At Startup"
What I do is create a shortcut that I place in shell:startup.
The shortcut has the following:
Target: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command "C:\scripts\script.ps1"
(replacing scripts\scripts.ps1 with what you need)
Start In: C:\scripts
(replacing scripts with folder which has your script)
You could create a Scheduler Task that runs automatically on the start, even when the user is not logged in:
schtasks /create /tn "FileMonitor" /sc onstart /delay 0000:30 /rl highest /ru system /tr "powershell.exe -file C:\Doc\Files\FileMonitor.ps1"
Run this command once from a PowerShell as Admin and it will create a schedule task for you. You can list the task like this:
schtasks /Query /TN "FileMonitor" /V /FO List
or delete it
schtasks /Delete /TN "FileMonitor"
This is really just an expansion on #mjolinor simple answer [Use Task Scheduler].
I knew "Task Scheduler" was the correct way, but it took a bit of effort to get it running the way I wanted and thought I'd post my finding for others.
Issues including:
Redirecting output to logs
Hiding the PowerShell window
Note: You must have permission to run script see ExecutionPolicy
Then in Task Scheduler, the most important/tricky part is the Action
It should be Start a Program
Program/Script:
powershell
Add arguments (optional) :
-windowstyle hidden -command full\path\script.ps1 >> "%TEMP%\StartupLog.txt" 2>&1
Note:
If you see -File on the internet, it will work, but understand nothing can be after -File except the File Path, IE: The redirect is taken to be part of the file path and it fails, you must use -command in conjunction with redirect, but you can prepend additional commands/arguments such as -windowstyle hidden to not show PowerShell window.
I had to adjust all Write-Host to Write-Output in my script as well.
Try this: create a shortcut in startup folder and input
PowerShell "& 'PathToFile\script.ps1'"
This is the easiest way.
Prerequisite:
1. Start powershell with the "Run as Administrator" option
2. Enable running unsigned scripts with:
set-executionpolicy remotesigned
3. prepare your powershell script and know its path:
$path = "C:\Users\myname\myscript.ps1"
Steps:
1. setup a trigger, see also New-JobTrigger (PSScheduledJob) - PowerShell | Microsoft Docs
$trigger = New-JobTrigger -AtStartup -RandomDelay 00:00:30
2. register a scheduled job, see also Register-ScheduledJob (PSScheduledJob) - PowerShell | Microsoft Docs
Register-ScheduledJob -Trigger $trigger -FilePath $path -Name MyScheduledJob
you can check it with Get-ScheduledJob -Name MyScheduledJob
3. Reboot Windows (restart /r) and check the result with:
Get-Job -name MyScheduledJob
see also Get-Job (Microsoft.PowerShell.Core) - PowerShell | Microsoft Docs

Copy ps1 into this folder, and create it if necessary. It will run at every start-up (before user logon occurs).
C:\Windows\System32\GroupPolicy\Machine\Scripts\Startup
Also it can be done through GPEDIT.msc if available on your OS build (lower level OS maybe not).
Be sure, whenever you want PowerShell to run automatically / in the background / non-interactive, it’s a good idea to specify the parameters
-ExecutionPolicy Bypass to PowerShell.exe
PowerShell.exe -ExecutionPolicy Bypass
I have a script that starts a file system watcher as well, but once the script window is closed the watcher dies. It will run all day if I start it from a powershell window and leave it open, but the minute I close it the script stops doing what it is supposed to.
You need to start the script and have it keep powershell open.
I tried numerous ways to do this, but the one that actually worked was from http://www.methos-it.com/blogs/keep-your-powershell-script-open-when-executed
param ( $Show )
if ( !$Show )
{
PowerShell -NoExit -File $MyInvocation.MyCommand.Path 1
return
}
Pasting that to the top of the script is what made it work.
I start the script from command line with
powershell.exe -noexit -command "& \path\to\script.ps1"
A relatively short path to specifying a Powershell script to execute at startup in Windows could be:
Click the Windows-button (Windows-button + r)
Enter this:
shell:startup
Create a new shortcut by rightclick and in context menu choose menu item: New=>Shortcut
Create a shortcut to your script, e.g:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -Command "C:\Users\someuser\Documents\WindowsPowerShell\Scripts\somesscript.ps1"
Note the use of -NoProfile
In case you put a lot of initializing in your $profile file, it is inefficient to load this up to just run a Powershell script. The -NoProfile will skip loading your profile file and is smart to specify, if it is not necessary to run it before the Powershell script is to be executed.
Here you see such a shortcut created (.lnk file with a Powershell icon with shortcut glyph):
This worked for me. Created a Scheduled task with below details:
Trigger : At startup
Actions:
Program/script : powershell.exe
Arguments : -file
You can see scripts and more scheduled for startup inside Task Manager in the Startup tab. Here is how to add a new item to the scheduled startup items.
First, open up explorer to shell:startup location via start-button => run:
explorer shell:startup
Right click in that folder and in the context menu select a new shortcut. Enter the following:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile
-Command "C:\myfolder\somescript.ps1"
This will startup a Powershell script without starting up your $profile scripts for faster execution. This will make sure that the powershell script is started up.
The shell:startup folder is in:
$env:APPDATA\Microsoft\Windows
And then into the folder:
Start Menu\Programs\Startup
As usual, Microsoft makes things a bit cumbersome for us when a path contains spaces, so you have to put quotes around the full path or just hit tab inside Powershell to autocomplete in this case.
If you do not want to worry about execution policy, you can use the following and put into a batch script. I use this a lot when having techs at sites run my scripts since half the time they say script didnt work but really it's cause execution policy was undefined our restricted. This will run script even if execution policy would normally block a script to run.
If you want it to run at startup. Then you can place in either shell:startup for a single user or shell:common startup for all users who log into the PC.
cmd.exe /c Powershell.exe -ExecutionPolicy ByPass -File "c:\path\to\script.ps1"
Obviously, making a GPO is your best method if you have a domain and place in Scripts (Startup/Shutdown); under either Computer or User Configurations\Windows Settings\Scripts (Startup/Shutdown).
If you go that way make a directory called Startup or something under **
\\yourdomain.com\netlogon\
and put it there to reference in the GPO. This way you know the DC has rights to execute it. When you browse for the script on the DC you will find it under
C:\Windows\SYSVOL\domain\scripts\Startup\
since this is the local path of netlogon.
Execute PowerShell command below to run the PowerShell script .ps1 through the task scheduler at user login.
Register-ScheduledTask -TaskName "SOME TASKNAME" -Trigger (New-ScheduledTaskTrigger -AtLogon) -Action (New-ScheduledTaskAction -Execute "${Env:WinDir}\System32\WindowsPowerShell\v1.0\powershell.exe" -Argument "-WindowStyle Hidden -Command `"& 'C:\PATH\TO\FILE.ps1'`"") -RunLevel Highest -Force;
-AtLogOn - indicates that a trigger starts a task when a user logs on.
-AtStartup - indicates that a trigger starts a task when the system is started.
-WindowStyle Hidden - don't show PowerShell window at startup. Remove if not required.
-RunLevel Highest - run PowerShell as administrator. Remove if not required.
P.S.
If necessary execute PowerShell command below to enable PowerShell scripts execution.
Set-ExecutionPolicy -Scope LocalMachine -ExecutionPolicy Unrestricted -Force;
Bypass - nothing is blocked and there are no warnings or prompts.
Unrestricted - loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the internet, you're prompted for permission before it runs.
I 'm aware that people around here don't need a tool like this. But I think it will be useful especially for novice users. Auto start tool It is a Portable freeware which designed to simplify the process to automatically launch an App or script when you login to Windows. It offers 3 different options for autostart
Task Scheduler
Startup folder
Registry run key
The best part of the tool is supports powershell scripts (.Ps1) . this means that you can run a Powershell script automatically at system startup with all 3 methods.

One thing I found. if you are using Write-Host within your PowerShell scripts, and are also using Task Scheduler (as shown in the posts above), you don't get all the output from the command line.
powershell.exe -command C:\scripts\script.ps1 >> "C:\scripts\logfile.log"
In my case, I was only seeing output from commands that ran successfully from the PowerShell script.
My conclusion so far is PowerShell uses Out-File to output to another command or in this case a log file.
So if you use *> instead of >> you get all the output from the CLI for your PowerShell script, and you can keep using Write-Host within your script.
powershell.exe -command C:\scripts\script.ps1 *> "C:\scripts\logfile.log"
https://lazyadmin.nl/powershell/output-to-file/
You can also run the script in the background, regardless of user login.
Within your task in Task Scheduler set "Run whether user is logged on or not", and then in the password prompt type your hostname\username then your password (In my case an account with Admin permissions).
I used Set-ExecutionPolicy RemoteSigned -Scope CurrentUser to get around the script execution problem. I still would have preferred to run it on a per-process basis though. A problem for another time.
My mission is to press a keyboard sequence, such as Ctrl +Shift +R, to restart a Windows Service.
I have a script which works fine in the PowerShell ISE, when launched with administrative privileges.
When I try with a PowerShell script it fails due to insufficient Administrative Privileges. It’s galling that I can get it to work with an old-fashioned bat file, but not PowerShell.
The root of the problem is that shortcuts to a PowerShell script have their Administrative privileges box greyed out. So far no work-around has overcome this privilege problem.
Any ideas?
One approach is to start another elevated PowerShell session within your script like so:
Start-Process PowerShell.exe -arg '-nologo -noprofile script.ps1' -verb runas
That should prompt to elevate the new PowerShell session. I think you should be able to set the -WindowStyle parameter such that the new window doens't appear (if you need that behavior). Note that you will need to specify the full path to your existing script.
You suggest you don't like solving this problem with a batch file (e.g. net start), I think because batch files are inherently more limited than powershell scripts. What you can do is wrap your Ps script in a batch file, though, for the sake of accomplishing your stated objective -- running a powershell script with a keyboard shortcut without access permissions issues. Try this in a batch file:
powershell set-executionpolicy remotesigned
powershell myscript.ps1
