HOWTO: Remove / Disable MDM (Mobile Device Management) policies

Microsoft's Mobile Device Management policies are setup on some laptops when Office is installed.  Jay has tried emailing Tech Services about this, but hasn't yet found the right person who knows either how to change or remove them.  Fortunately, it's not terribly difficult to fix:

• Click Start, then search for "Local Group Policy Editor"
• Use Local Group Policy Editor, and navigate to: Computer configuration > Administrative Templates > Windows Components > MDM > Disable MDM Enrollment
  • NOTE: This doesn't remove existing MDM policies, just prevents new ones from being applied
• Remove the "Work or School" Microsoft account (see https://www.onmsft.com/how-to/how-to-manage-personal-work-and-school-accounts-in-windows-10)

The next time you start an Office application, you're likely to get a prompt to log in.  You can select either the "use for this application only" or "allow my organization to manage my device" - either way, the MDM policies should not be re-applied.
