My Help and Support was not working after doing some automatic updates of Windows 7 Professional. I tried a system restore back to an earlier time according to one entry in this forum, that didn't work.
Well, I tried your Scannow trick to repair corrupted files and it worked like magic.
Thanks so much for your suggestion put here a while ago, it really helped.
I wish doing automatic windows updates wouldn't mess things up sometimes but at least now I know what to do to fix this when it happens again.
