Remove Domain Group Policy from PC in a Workgroup

Scenario:
You build a PC using you favourite deployment method which adds it to a domain. The PC gets Group Policy but is then removed from the domain.

The computer policies are NOT removed... By design or a design flaw who knows.

Solution:
To remove the policies launch "regedit" and browse to:
"HKLM\Software\Microsoft\Windows\CurrentVersion\Group Policy"
Remove any keys starting with "S-".

Open the key "GroupMembership" and delete the entries starting with "S-" that you removed above.

 

Reboot and you are now policy free.
