XP Reboots After System Update After Loading Mup.sys

[Claude]

I installed the latest system update last Sunday and now Windows XP
reboots after loading mup.sys. I reinstalled XP (with SP2) using the
"repair" option but the same thing happens. I have run chkdsk, reset
CMOS. Nothing works.

Would there be any point in backing up the registry and then copying
the original registry from c:\windows\repair? If that worked I could
then copy a previous registry from the System Volume Information
folder. I just found an KB article about that -
http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q307545

I'm trying to avoid installing a new copy of the OS and having to
reinstall everything, which might night even work. Any other
suggestions?

Hi,

I have experienced the same problem on several PCs. Sometimes I was
able to start in safe mode, but in worst cases computer acted almost
dead. In this cases I didn't even get windows startup menu (to choose
safe mode or similar).
But everytime the same steps solved the problem:
- boot computer from Windows CD and choose repair (R)
- from command prompt run: chkdsk /r
- when checkdisk finishes, remove Windows CD and boot WindowsXP
normally.

Before that I tried zillion tips I found on web, but none of them
helped.
