Why does the “open with” window keep popping up in Vista Home?

I am using Vista Home. When I click on Accessories, defrag, and anything else, the open with window keeps popping up. Can anyone tell me if system files are missing?

    Does this happen only to system tools (defragmenter, system restore etc.) or other programs as well? When did it start happening? Did you try system restore?
