My VS 2012 Update 1 starts completely slowly, even if I upgraded to Update 2, it is still the same. So, I think (maybe wrong), because some extensions in VS 2012 crashed, I can’t remove them.

In the picture, I have 2 extensions damaged (the delete button is disabled):
- Microsoft Web Developer Tool.
- Visual Studio Extensions for the Windows Library for JavaScript.
Is there a way I can remove both?
I also follow the prompt in the lower right corner for removal in "Programs and Features", but I can not find.
