Hey guys, well here's my story. On my computer I had Windows XP pro sp2, and I reinstalled it with a different CD (windows Xp home), because I din't have the other XP pro cd or key. As the 30 day count down.. counted down, I hadn't bothered to get the other pro cd or another one. So I hadn't activated windows yet, and now it's on the last day and I got a crack off a friend.. yes.. I wish I didn't do that. But before I ran it I made a restore point and a backup of the registry. Yeah, so I ran the crack ( I can't remember what it was called but the guy who made it's name was chinese) It did something to winlogon.exe, and It made a backup. SO the machine rebooted and tried to go back into windows, but it just gets to a different logon screen to home, displays a stop error then reboots. What can I do without formatting?
