NinjaOne: Custom fields and Windows Activation.

Just as a warning before using this script, it is not the quickest script to run, and I would suggest only running the script once per week on a schedule.

This requires a custom field with a text type, read only permissions for technicians, and write only permissions for scripts

$LicenseInfo = Get-CimInstance SoftwareLicensingProduct -Filter "Name like 'Windows%'" | where { $_.PartialProductKey } | select Description, LicenseStatus 
            Switch ($LicenseInfo.LicenseStatus) {
                0 {$LicenseStatus = 'Unlicensed'; Break}
                1 {$LicenseStatus = 'Licensed'; Break}
                2 {$LicenseStatus = 'OOBGrace'; Break}
                3 {$LicenseStatus = 'OOTGrace'; Break}
                4 {$LicenseStatus = 'NonGenuineGrace'; Break}
                5 {$LicenseStatus = 'Notification'; Break}
                6 {$LicenseStatus = 'ExtendedGrace'; Break}
            }
