Unsuccessful after following your recommendation
Functio and chi-va,
I am experiencing the same EXACT problem on my Windows XP Pro Dell after running Spybot on 7/3/2008. All of my Windows account will not login. They begin, then immediately logoff.
I followed your directions to the "T' and was unsuccessfull. I booted from a 3rd party utility CD which allowed me to browse my hard drive. I ran the regedt32 and followed your recommmendations by loading hive called "TEST". Continued with your steps until complete, rebooted from my HD and attempted to login. It started by displaying my desktop then immediately logged off. Am I missing a step or are there additional steps to follow that I may have missed. PLEASE HELP
