I came across this bit of software while looking for a way to report on all the GPO's that have been set and best of all it is free.

Some blurb
Specops Gpupdate makes your life as an administrator MUCH easier providing operations such as update of Group Policy Objects (gpupdate or secedit /refreshpolicy), remote restart, wake on lan (WOL) and remote shutdown.
All operations are available in the Active Directory Users and Computers interface and through Searches of Active Directory. Even entire OUs can be selected.
After performing a gpupdate or secedit /refreshpolicy, remote restart, wake on lan (WOL) or remote shutdown, you will get instant feedback in a graph.
If you have used it can you let me know if it is any good.
cheers
