i just spent 3 hours to uninstall KB2533552 and KB976002. it works for both. here it is: (i found this on
http://poweradmin.se/blog/2010/03/1...-kb976002-the-microsoft-browser-choice-screen written by chris. i just wanted them uninstalled, not to reinstall other updates and it worked, the updates didn't reinstall, so i skipped steps 8-12.)
( be patient

)
1. Go to C:WindowsServicingPackages
2. Find the .mum files relating to KB 976002 and KB 253352
3. Take ownership of them, give yourself full control (it took me a hell of a time to figure it how, because i don't know much about these things, so i assume that there are others like me, so: right click-->properties-->security-->advanced-->owner-->edit-->and here i have 2 things: Administrators (--name of my computer--\Administrators) and Name of my computer (--name of my computer--\my name [i think it's the user's name]); i selected the second and clicked Apply-->ok [[it works for Administrators too]] ... do it again: Properties-->security-->advanced-->change permissions-->DESELECT "Include inheritable permissions for this object's parent"-->add-->click on TrustedInstaller-->remove-->click Users (that's what i chose; it works on Administrators too)-->edit-->select Full Controll-->ok-->apply-->yes-->ok-->ok-->ok. DONE. Now YOU have full control of files
4. Open Control Panel, programs, Installed Updates
5. Find KB 976002 or/and KB2533552 and right click; Uninstall is not available. Important: Do not close this window, to avoid re-verification of the checksum of the .mum files.
6. Go back to the .mum files for KB976002 and KB2533552. Edit them both with notepad, change permanance=”permanent” to permanence=”removable”
7. Go back to the Installed updates list, hit F5, right click KB 976002. Uninstall is now available.

then reboot
Misschien dat hierboven genoemde je kan helpen met het verwijderen van die update?
