When you try to uninstall Office click2run 2010 using kb290301 (MS fixit), you get an error stating problem with client virtualisation.
Solution:
Start> Run> Services.msc> Client virtualisation> properties> startup type> Disable\manual> Stop the service> Ok
Now try restarting system and then try using FIXIT from kb290301
As of now i was not able to find any articles or threads.
