I have been having this trouble for quite some time now.
After searching many of the other forums, none of them have provided a solid fix for this yet. I have tried downloading the apparent "fix" off various other forums and they have either been invalid or a missing link, even Microsoft doesn't have it!!!!!
I wanted to know if someone has got an actual fix for this as it is grinding my computer to a halt sometimes. Forget watching Youtube and even simple tasks!
