Touted recently as the “Best SITE EVER!!!!!” for researching Group Policy settings (and I have to agree), the Group Policy Search site, provided by MSDN and powered by Windows Azure, has just been updated to include the new GPO settings for Windows 8 and Windows Server 2012.
I know you’ll want to bookmark this site RIGHT NOW, so here’s the link: http://gps.cloudapp.net/
