If you want to try a 98 to 7 "upgrade" it will be interesting. I was bored one day and took a spare box, barely able to run 7 and wiped it. I installed 98se and did all the drivers
and updates. Then I upgraded to XP. Drivers and updates again. Then Vista. You know the drill.
When I upgraded again to 7 it worked. Without cleanup I was at over four times the disk space and under half the performance of a clean 7 install on the same box.
The moral of the story --if you have the installation media for the Vista to 7 upgrade like you must to do what you are asking to do. Perform a clean install and use that disk when prompted.
