Please Help Spybot Community Logon, Logoff Loop

[Egemna]

After running a scan on Spybot 1.3 I encountered the extremely annoying log on/off loop. Currently, I have tried nearly every solution, from Bart PE, boot up disk, and even tried to run a 'system recovery' all to no avail. Everything failed, eventually I used my other computer's hard drive to access my files and found out that I'm actually missing almost every key on the Winlogon registry tree. Now my only question is does anyone know how to recover or restore these keys?

Any other solutions aside from the ones I mentioned would also be helpful.
