Local Group Policy in Windows 7 – Roll back to default settings?

As far as I know there isn’t an easy way to revert back to the default settings.

You can do the following though:

With the Local Group Policy Editor open expand to the following node: gpedit.msc

Computer ConfigurationAdministrative TemplatesAll Settings

and sort by the State column.

Any policy that is set using that editor will show on top.
Repeat the same process for the User Configuration node.

If they set anything else in the Windows Settings or Software Settings node you’ll have to look at each
option and know which one is set or not.

If you are connected to a domain, the domain will override any conflicting settings that are set on the
local machine.

To prevent someone from making changes to the local group policy remove their user account from
the Administrator group.
