According to this site---"If you use Windows XP and havenít yet updated your system with the applicable security updates that Microsoft issued Tuesday, you might want to hold off for a bit. Turns out, a non-trivial number of XP users are reporting that their systems suffer from the dreaded Blue Screen of Death (BSoD) and fall into an interminable reboot loop after installing the latest batch of patches from Redmond."
Before I knew about this problem, I downloaded this update (KB977165) and installed it and got a BSOD on reboot. Info on this screen was:
10digit #, then in parens ( 10digits, 10 digits, 10 digits, 10 digits).
ctoss2k.sys - address F64FC57A base at F64FA0000 Data stamp 3E81578E.
Then on the next line--- "dump of physical memory" msg.
When I rebooted, pressed the F8 key, I went to the resart page that allows you to reboot in normal mode, safe mode, etc. I selected the mode "last know good configuration" and rebooted.
Since then my system has worked fine. My question---is there a way to undo this windows update fix without having to go to the repair screen/recovery console suggested in the 5 steps in the url link above?
