Update KB968389 crashes machine

Running windows XP SP3 on a Dell dimension 8400. Microsoft Updater
downloaded KB968389 on 8/18 and tried to auto install it. the auto reboot
failed. When I tried to power up the machine the next day I got to the
Windows screen and then the machine just hangs with a blank grey screen and
no lights on the keyboard.

Successfully restarted machine in Safe Mode. Went to <Control Panel>
<Add/Remove Software> and uninstalled that one update. Restarted machine and
it booted fine. Tried to manually install KB968389 using <Microsoft Update>
<Custom install> AFter install reboot once again failed. Repeated the Safe
Mode boot and uninstall and all is well.

Filed a Microsoft problem report and all I got back was some self-help
suggestions and an offer to pay Microsoft $59/Hr for the priviledge of having
them help me solve the problem their update appears to cause.

Any ideas?

This update is crashing my HP G70t-200 with Vista 64-bit OS. I'm no
getting what Microsoft Security Advisory (973811) has to do with thi
issue. Any ideas

I'm having very similar problems. Only I haven't been able to load into Safe
Mode. And I haven't been able to load Windows Setup from CD or any XP-based
boot discs. Mine's a home-built system that's been running perfectly for 3
years. I'm going to try to replace the updated files as given here:
http://support.microsoft.com/kb/968389 and see if that helps. I have no idea
if it will or not, though.

That update will not download on my computer. I guess I am lucky since it
crashes other computers. What is the update supposed to DO?
I only went back to load it after not being able to install the latest
download: kb951847, which downloads and fails to install several times. I
thought maybe the previous (some time ago) 968389 failure was necessary to
install the new download which has something to do with Net Framework. It
says it is critical but will not install. Error message here is Ox643 for
KB951847. Between home and work I have 5 PC's . The time to play with all
these updates is becoming ridiculous, every two days there is something new
that wastes my time. I was visiting my uncle in NJ who has only Apple
machines and the whole time I was there no updates, no downloads, just works.
I ask him how long has it been since he had a notice of updates, and the
reply was months ago, he did not really remember. Next machine for my home
is APPLE!
