  • Configure ‘Allow logon locally’ automatically using PowerShell and Microsoft Intune
    I know Microsoft Intune has the ability to configure this particular user rights assignment natively already.

This solution does something else. This solution grabs the currently logged on user and configures the ‘Allow logon locally‘ policy to ONLY allow this very user as well as Administrators to be able to log on locally.
