Sure!! Twice for me also. However it was not vista's doing in both cases.
The Ist time I installed vista it was a free upgrade I recieved when I purchased my current desktop. ( It was BAD!!! ) I soon went back to XP.
I re-installed in Sept. & wondered what all the gritching was about. It was great!!!
I had installed ontop of XP to save programs I never used & decided to clean house early this year . I did a second re-install this time &
sent all of my old stuff to never-never land & it has been super. I just like my disk lean ( store about every thing on an external hard drive).
With a few tweeks & some freeware Vista has been good to me. My only gripe is the Defrag. which Auslogics kindly helped with. I am
now a happy camper.
