MS06-15 is a bit of a nightmare if you include HP Share-to-Web in your install images

I'm not having the best day today due to most of our machines at work having a lot of HP software that conflicts with the original release of MS06-15. I ended up creating a registry file as suggested in KB 918165 as a temporary workaround with the known bad Nvidia and HP entries. You can cut and paste this into a '918165-xp.reg' text file in Notepad and import it if you like:

If you are running Windows 2000 and have trouble with the v1 release of MS06-15, you can simply remove the '0x401' from the end of those CLSID's because the calling conventions changes between the 2000 and XP kernel.
