One of the more annoying “features” of Windows XP is its insistence on launching AutoPlay when you insert or attach certain types of media to your PC, like CD discs or USB thumb drives. While AutoPlay can be temporarily disabled by holding down the Shift key after inserting a CD, for example, you may want to consider disabling the feature completely.
AutoPlay can be disabled via a Registry hack, but an easier method also exists. The free Tweak UI PowerToy from Microsoft makes it easy to disable AutoPlay for the drive letters of your choice at the click of a button. After installing Tweak UI, just expand My Computer > AutoPlay > Drives and uncheck any drive letters for which you want AutoPlay disabled. Click OK and then never worry about being harassed by AutoPlay settings on those drives again. If you change your mind, you can always re-enable AutoPlay by checking the associated driveusing Tweak UI.
