ok so, i reformatted my hardrive, and reinstalled XP profesional. it has been great, i was updating windows and getting all my security updates ect. then its time to install service pack two. wont let me. it starts then comes up with an error, something like "C:\windows\system32\cmd.exe" is already in use please exit all programs and try again. nothing open. i think that it might be worth it since i have put all my stuff back on the computer jsut to reformat again and try it again. but just wanted to see if you had any reccomendations first? anyways hope this is in the right place, if not feel free to move it. thanks alot!
