When cleaning up a computer from spyware I am no longer able to login to Windows XP. I get to the login screen and click on any username, it acts like it is logging in but then it will say saving settings and logging out.
I have tried copying userint.exe to wsaupdate.exe through the recover console but that didn't help. While the computer was on the login screen I tried connecting to the registry by using registry editor and "connect network registry" on another computer but that didn't work. I also can't get into safe mode probably because of a device driver is preventing me from getting to the login screen. I used Hijack This and I think I deleted a registry value that is needed.
I backuped up the registry before trying to remove all the spyware but now I can't access it to restore it. Is there a way to restore the backup registry or be able to edit the registry from the recovery console or another means that is not logging onto the computer?
I can try doing a repair install but I don't want to risk deleting files or making programs inoperable. What options do I have to fix the registry or be able to login?
