After the installation of some software my PC was fucked up.
So, smart as I am

I created a system restore point BEFORE this installation.
After my pc was fucked up, I did a system restore. Guess what? I have MANY MANY shortcuts double (2) That is not a real issue, however, also items in configuration panel are double. And even my icq contacts are double etc. I searched for all (2) files, and deleted those. That helped, but still to many errors...So I have to do a format c:\....
I think I have backed up everything, so wish me luck
(oh I tried another system restore from another date, that didn't help either....)
