Thanks for your help. I did a recursive xcopy on my user folder and other important folders. Then I ghosted back my original installation. Setting up my computer has taken several days and I'm still not finnished.

One important thing about xcopy.
XCOPY DOESN'T COPY HIDDEN FILES/FOLDERS AS DEFAULT!!!!!!!
You have to add a switch for that.
This painfull experince didn't copy my private appdata in my users/users/appdata folder. Sucks big time.
