Faster Booting by cleaning out Windows Pre-Fetch Folder
One of Microsoft's big selling points for Windows XP was that it loads applications much faster than its predecessors. To accomplish this feat, Windows XP uses what is called the "Prefetch technique," in which the operating system gathers information about each program that you launch and stores that information in the \Windows\Prefetch folder. Then on subsequent restarts, Windows XP uses the information in the Prefetch folder to essentially preload parts of those programs at boot time. Thus, when you launch your application, it appears to load really fast.
Type Prefetch in the Open text box and click OK.
