I have been using WinClean to remove my Temporary Internet Files, Cookies, History, and Temp folders on my XP computer. It is a simple batch file. You click it and then reboot and it removes the old ones and Windows creates new ones. You will see the command window pop up for a second or two. Remember to use Disk Cleanup first!! Then delete all your Cookies, History, and Temp folder's files. If you do not do this it will take forever for WinClean to do it's job!! (And an hour to start Windows.)
