How to open Windows Powershell (Elevated) without admin rights? - powershell

I wanted to turn on The Windows Subsystem for Kali Linux. But it requires me to execute powershell as admin.
This is for executing a command on my pc. I have tried task scheduler but it did not work.

An "elevated" Command Prompt or Powershell session is, in fact, a session with admin rights. If you do not have credentials that grant you admin rights on the system, you cannot open an elevated session. There is no way to circumvent this. Talk to whoever is the administrator of your computer.

Can you put a line in the PS to elevate the commands?
# Set the variable
$cred = Get-Credential -credential domain\privaccount$
then depending on the comment, add
-credential $cred
For example:
$cred = Get-Credential -credential domain\MyAdmin$
Get-ADUser -Filter * -SearchBase $ou -credential $cred
What command are you trying to run elevated?

Powershell script guidance

I am looking for powershell code for installing software packages in remote machines which are in ADS domain.While installing I have to pass my admin credentials. How can I do this?
Guidance required
You can store your password to be used on a remote computer using the Get-Credential command like this:
`$Credential = Get-Credential
You'll see a prompt like this appear:
I would recommend storing the applications you need to install in a central place, that all of your remote devices can reach. I'll assume you've stored them in the UNC Path: \\FileServer\Application
Let's say you wanted to install 7Zip and had it present in that path:
$Credential = Get-Credential
$Computers = 'RemotePC1', 'RemotePC2'
Invoke-Command -ComputerName $Computers -Credential $Credential `
-ScriptBlock {& \\FileServer\Application\7Zip.msi} -ArgumentList '/q INSTALLDIR="C:\Program Files\7-Zip"'

Unlocking an AD user with Powershell

I’m new to Powershell and am struggling to make a script work. I’ve read many articles here on Overflow and elsewhere and don’t see what I’m doing wrong. Any help would be appreciated.
I'm trying to create a script that will unlock an AD user remotely while I'm logged-on to may computer as a local admin. Here's my script:
Import-module Activedirectory
New-PSSession -ComputerName <Remote ComputerName> -Credential
<domain admin credential>
Import-Module Activedirectory
Unlock-ADAccount
Read-host “Press any key”
I try to execute this from my computer logged-on as a local admin, but pass domain admin credentials. The script is run as an administrator in Powershell. After I enter my domain password and indicate which user I want to unlock, the message I get is: “Insufficient access rights to perform the operation”.
If I run this code interactively in Powershell, line by line, it will unlock the account. If I run a script asking only to see if the user is locked, it will give me an answer. If I run the above script from my computer logged-on as the domain admin, it will run and unlock the user.
I don’t understand why it will not run when I’m logged-on as local admin, given that I’m passing domain admin credentials. Any help would be appreciated.
You're creating a PSSession, but not using it. Try something like this (untested):
$computer = "test1"
$cred = Get-Credential
$user = Read-Host User to unlock
$sess = New-PSSession -ComputerName $computer -Credential $cred
Invoke-Command -Scriptblock { param($ADuser) Import-Module Activedirectory; Unlock-ADAccount -Identity $ADuser } -ArgumentList $user -Session $sess
Read-host “Press any key”
Although you could create a PSSession, if you have RSAT installed and have access to the ActiveDirectory module there is no need to do that. Instead, just use the credential parameter on each AD cmdlet. For instance, to unlock a user account using alternate credentials, use the following:
Unlock-ADAccount -Identity username -Credential (get-credential)

win32_process create fails with Unknown failure for service account user

I have a windows service account user, using which i'm trying to create a background process using the WMI win32_proces. But fails with Unknown Failure.
(Tried this with administrator, nonadmin, domain admin, domain nonadmin users. works fine)
$process = [WMICLASS]"\\$computername\ROOT\CIMV2:win32_process"
$processinfo = $process.Create("powershell.exe -WindowStyle Hidden test.ps1")
Write-Host $processinfo.returncode
As explained in this msdn blog post: Win32_Process.Create fails if user profile is not loaded, the WMI call is hardcoded to access the users profile through the registry.
If the user profile is not already loaded in HKU, WMI tries to load it into the registry using RegLoadKey.
This fails unless the user account in question have the following privileges on the local machine:
SeRestorePrivilege
SeBackupPrivilege
So, either
Grant these privileges to the account in question
Call LoadUserProfile for the user in question prior to calling Win32_Process.Create
Or use Start-Process instead of WMI!
# Set up service account credentials
$Username = "domain\svcaccount"
$Password = "7oPs3çürEûN1c0deZ"
$Credential = New-Object pscredential -ArgumentList $Username,$(ConvertTo-SecureString $Password -AsPlainText -Force)
# Establish a session on the remote machine
$RemoteSession = New-PSSession -ComputerName $computername -Credential $Credential
# Launch the process with Start-Process -LoadUserProfile
Invoke-Command -Session $RemoteSession {
Start-Process 'powershell.exe' -LoadUserProfile:$true -Argumentlist 'test.ps1' -WindowStyle Hidden
}
# Cleanup
Remove-PSSession -Session $RemoteSession
Remove-Variable -Name Username,Password,Credential
To Mathias suggestions in below comments:
Start-Process works in background only when invoked through interactive prompt. If run from a .ps1 script, the process created through start-process exits if the .ps1 script exits.
Inside your script. You can create a New-PSsession and then pass this session to invoke-command to trigger start-process.
But again to use New-PSsession and ExitPSSession, you must have Enable-PSRemoting and other setting enabled if you are lacking permissions. http://blogs.msdn.com/b/powershell/archive/2009/11/23/you-don-t-have-to-be-an-administrator-to-run-remote-powershell-commands.aspx

Restart IIS on remote machine using Powershell

I have a TFSserver and a QAserver. I am using autodeployment using TFS and have a powershell script that do the requirement.
But I have a issue in restarting the QA server IIS from the same power shell script.
i am doing the following set of commands for restarting the IIS.
/*struser is in the administrator group of the QAserver
$cred = New-Object System.Management.Automation.PSCredential ("$QAserver$struser", $password )
$session = new-pssession $oceane_server -Auth Negotiate -Credential $cred
/* Some deployment script */
invoke-command -session $session -ScriptBlock {iisreset /stop}
Following error appears :
Access denied, you must be an administrator of the remote computer to use this
command. Either have your account added to the administrator local group of
the remote computer or to the domain administrator global group.
I could not find the solution for this. Any help would be appreciable.
The quick work around is to open all the ports of your server and run iisreset [MACHINENAME] /stop.
For powershell remoting, I use credssp because it allows the double-hop. Also, did you set your execution policy to bypass?
Set-ExecutionPolicy Bypass

Invoke-Command and Start-Process Issues

I'm trying to execute the following script:
$Cred = Get-Credential
Invoke-Command -Computername Localhost -Cred $Cred -Scriptblock {Start "Notepad.exe" -Wait}
Well, the notepad comes up no problem as Administrator but it is not visible in the current user's account.
I think it's not possible to see gui in an interactive session with different credential, it live in another user session.
Workaround:
start-process notepad.exe -Credential $Cred
I've run into this problem with PS Remoting and could not find a way to get an app running under one set of credentials to show up on the interactive desktop of a different user. I eventually gave up and used SysInternals utility psexec along with its -i parameter.
