Solved Run PS1 files (double click) on Windows 11

Hello,
On Windows 10 I was able to modify the file association by using the following command :

Set-ItemProperty -Path "Registry::HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\Open\Command" -Name '(Default)' -Value '"C:\Program Files\PowerShell\7\pwsh.exe" -noLogo -ExecutionPolicy bypass -file "%1"'

This command no longer works on Windows 11 because the registry location does not exist. I need a way to make PS scripts to run with a double click and the solution must be in a form of a command , No GUI solutions please.

Thanks

Example. Running PS_ise.
Any .ps1 file -> Properties: Change PS_ise

# .ps1
If (!(Test-Path "HKCR:\PS_ise.ps1\DefaultIcon")) {
New-Item -Path "HKCR:\PS_ise.ps1\DefaultIcon" -Force
}
Set-ItemProperty -Path "HKCR:\PS_ise.ps1\DefaultIcon" -Name "(default)" -Type ExpandString -Value "$ExtLibraryIcons,-12" -Force
Set-ItemProperty -Path "HKCR:\.ps1" -Name "(default)" -Type String -Value "PS_ise.ps1" -Force
Set-ItemProperty -Path "HKCR:\PS_ise.ps1" -Name "(default)" -Type String -Value "File .ps1" -Force
If (!(Test-Path "HKCR:\PS_ise.ps1\Shell\Open\Command")) {
New-Item -Path "HKCR:\PS_ise.ps1\Shell\Open\Command" -Force
}
Set-ItemProperty -Path "HKCR:\PS_ise.ps1\Shell\Open" -Name "FriendlyAppName" -Type String -Value "PS_ise" -Force
Set-ItemProperty -Path "HKCR:\PS_ise.ps1\Shell\Open\Command" -Name "(default)" -Type String -Value '"C:\Windows\System32\WindowsPowerShell\v1.0\powershell_ise.exe" "%1"'-Force

Thanks abactuon !! - I modified your script and everything is working as needed

Hi - sorry to necro a thread, but running into this with machines that need to run by default from group policy. We've tried every registry entry we can think of and are going to test the script above. Nothing works on Windows 11 except manually setting it in control panel, which we can't do. These machines have to run a powershell created by another application dedicated to the user who badged in to function correctly. Has anyone else weaponized this for widescale deployment?

Download SetUserFTA, and create a new FTA (file type association). Double-clicking on *.ps1 will auto-run from Explorer.
