It seems my system will not move past the windows is starting up... phase of logging in with any logonscreen active.
The biggest problem is trying to boot to the previous good configuration does not help, it results in the same behavior. Is there a way to get rid of logonscreens without actually booting into windows? since I can only get to a repair console. Even safe mode does not work, it also hangs. The only way I have been able to get rid of the problem has been to run setup from the xp cd and then choose the repair option of the setup program. I would like an easier way, since this kills all my updates.
