MagicTweak 2.80 New
 

MagicTweak is a special program designed to optimize and personalize Microsoft Windows. It provides one-stop, instant access to a variety of Windows settings that can be altered for a friendlier Windows environment.This unique software makes it easy to tweak hundreds of hidden settings in Windows XP/2000/Me/98, so there is no longer any need to dig through the registry looking for that specific setting (from the Start Menu, Desktop, IE skin, System Icon to System Security) that just doesn't seem to be there.
