Computer freezes immediately during bootup after windows update

[Guest]

I installed the updates today and my computer froze during the usual reboot.
All attempts to boot windows using all of the F8 options fail with an
immediate system freeze before the windows splash screen (normal boot modes)
or a spontaneous reboot (safe mode).

Before the problem, I had a fully patched and updated system.

I installed the following:
Critical stop error patch
root certificates
DRM update
malicious software scanner

All boot attempts immediately lock the computer before the windows splash
screen. safe mode boots result in a spontaneous reboot. I can't get into
the computer to even check the boot log. My winXP cd is an original winXP
home cd (before SP1 even) so I'd rather not have to completely re-install
windows.

Hardware:
Athlon 64 X2 4400
2 gig ram
boot drive is SATA
Nvidia nforce3 chipset motherboard
nvidia 6800GT video card
creative audigy2 ZS sound card
onboard networking

The computer worked fine before these updates. I put in one of those linux
live CDs to make sure it wasn't a hardware failure, and the computer runs
linux just fine so it's the windows installation that doesn't work anymore.
Microsoft seems to want $59 to even report the problem via email, so any help
will be appreciated.

More info - I used linux to browse the windows volume and found this info.

No bootlog is created during "logged" boot mode, so the bootup aborts before
the bootlog is created.
Windows update log shows the following updates successfully installed:
KB929338
KB929399
KB890830
Root Certificates

Help anyone? Microsoft?

I don't see why any update would effect the "Last Known Good Configuration"

You should probably try this 'manual' version of a system recovery.

Add one more person... to the list of the MS auto-disabled. I've never had
to do such an uninstallation before. I assume I just copy back the old kernel
files and reboot. That one can't even get into Safemode...to do this has made
this extremely difficult to debug.
