"do a clean install" - Oh, PUH-LEEZ! How many people want to wipe out who know how many gigabytes or even terabytes of data & programs because Redmond can't design and code a decent installer? And, PUH-LEEZ, don't suggest you should back up your data first. What good is that is you've lost all of your programs?
In my opinion, the install should simply overwrite the previous versions and not start with fresh rust.
