Scripting

I'm trying to find windows 10 machines which are and are not activated. I found a powershell script that works but I have not be able to get it to work as customer inventory.

here is the powershell script

Get-CimInstance SoftwareLicensingProduct -Filter "Name like 'Windows%'" | where { $_.PartialProductKey } | select LicenseStatus

I've tried

ShellCommandTextReturn(ShellCommandTextReturn(c:\windows\sysnative\WindowsPowerShell\v1.0\powershell.exe -command "Get-CimInstance SoftwareLicensingProduct -Filter "Name like 'Windows%'" | where { $_.PartialProductKey } | select LicenseStatus")

ShellCommandTextReturn(cmd /q /c powershell -command "Get-CimInstance SoftwareLicensingProduct -Filter "Name like 'Windows%'" | where { $_.PartialProductKey } | select LicenseStatus")

ShellCommandTextReturn(cmd /q /c powershell.exe -ExecutionPolicy Bypass -Command "Get-CimInstance SoftwareLicensingProduct -Filter "Name like 'Windows%'" | where { $_.PartialProductKey } | select LicenseStatus"

None of these work. Could someone please help with this? 

Thanks
