gateway desk top computer. had windows vista on it, upgraded to windows 7. then later on computer was messing up so i reinstalled windows 7 and stupidly did not save the partition. so all my stuff was lost.pictures, vista, it all. had to call a number for windows they walked me through validating the windows 7 again because doing what i did it messed that up to. so now my computer runs slow as heck because the version of windows 7 32 bit is installed and my computer is always looking for 64 as in more memmory i assume which makes it clitch up. but i need vista back on and someone to try and recover windows.old. which i cannot find anywhere.
