cf. your earlier thread here:
Did you EVER have a beta or Release Candidate build of WinXP SP3 installed?
What anti-virus application or security suite is installed? What
anti-spyware applications (other than Defender)? What third-party firewall
(if any)? Were any of these applications running in the background when you
installed or uninstalled any version of WinXP SP3?

Support for Windows Update:
For home users, no-charge support is available by calling 1-866-PCSAFETY in
the United States and in Canada or by contacting your local Microsoft
subsidiary. There is no-charge for support calls that are associated with
security updates. When you call, clearly state that your problem is related
to a Security Update and cite the update's KB number (e.g., KB123456).
LOOK! => If your problem relates to a Cumulative Security Update for IE,
call the above number and ask to be transferred to the Consumer IE7 queue
(which is 47830).
For more information about how to contact your local Microsoft subsidiary
for security update support issues, visit the International Support Web
For enterprise customers, support for security updates is available through
your usual support contacts.
