When i click on my computer, my pc does nothing... What could be the cause of that? I tried a joke with my little sister, which involved editing the register, and making a new DWORD object called NoDrives, but when i tried to undo this, i accidentally erased the wrong DWORD object, called NoDrives with something behind it. I`m using Windows XP, could anybody please tell me which DWORD object that could be, and what it`s for, and how to recover it?
