I am going to go out on a limb here, and suggest a tool that was designed for NT, but may work with XP.

ftp://ftp.microsoft.com/bussys/utilities/hotfix/

Try that FTP link. Download the hotfix.exe file. then the txt file. txt has the commands for usage.

I believe though if you installed these hotfixes as a group, that unless you have a restore point, uninstalling them might be impossible. In fact MS recommends reinstalling the OS if you cannot remove the troubled hotfix:

It says for 2000 but I believe it is applicable to XP.
