Like Group Policy, the Group Policy Management Console (GPMC) has changed with new versions of Windows.
GPMC version 1.0 worked with Windows XP and Windows Server 2003.
Group Policy provides a convenient and effective way to manage both preferences and settings for computers and users.
With Group Policy, you can manage preferences and settings for thousands of users or computers in the same way that you manage preferences and settings for one computer or user—and without ever leaving your desk.
Prior to deploying a change, you can save the state of Group Policy.
If something goes wrong, you can restore Group Policy to its original state.
If a policy isn’t applicable to a particular version of the Windows operating system, you can’t apply it to computers running those versions of the Windows operating system.
