How to run unsigned PowerShell scripts on start up with Group Policy

Create .bat file

Create remove_appx.bat file inside netlogon share folder

del c:\windows\temp\remove_appx.ps1
copy \\shebangthedolphins.net\netlogon\SCRIPTS\remove_appx.ps1 c:\windows\temp\ /Z /Y
%windir%\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -File c:\windows\temp\remove_appx.ps1
del c:\windows\temp\remove_appx.ps1

This .bat will copy the PowerShell script to the Temp folder and Execute it. At the end, the ps1 file will be removed.

Create the PowerShell script file

Create remove_appx.ps1 file inside netlogon share folder

Set-Content -Path 'C:\remove_app.txt' -Value 'OK'	#check if the script has been executed
