Sometimes viruses or people use Group Policy against us and we need to reset it back to the default. It can control access to a number of things in windows from logon scripts to access to the screensaver settings. Resetting it is actually pretty simple, which is why you shouldn’t rely on it solely to guard your network.
Group Policy
secedit /configure /db reset /cfg “c:\windows\security\templates\setup security.inf” /overwrite
Also, you should delete the registry.pol file if it exists:
del c:\windows\system32\grouppolicy\machine\registry.pol
Don’t forget to reboot! All the group policies should now be reset to default.
