Windows 10: Clean install or not

I installed W10 over virgin copies of W7 Pro on two computers. After a clean disk to get rid of all install files I will have pretty much a clean install. What would be the advantage to now do a complete clean install ? Everything seems to be working ok.

Can not clean install or reset windows 10

Ill do this one. MS Chat did the last two and burned them to a disk

Ill leep my fingers crossed

 

Can not clean install or reset windows 10

I used power iso and its burned to a disk and yes I changed the boot sequence. It still boots up into Windows 10 desktop. I even took it out of fast boot

 

Maybe none that you'd ever notice.

You say virgin, which implies little use.

But some folks can't stand the doubt and the possibility of being "unclean", so that will likely govern your decision and be reflected in any further comments you might get.

And I think a clean will prevent you from reverting to W7 Pro unless you have made an image file of that installation.

 

These were TechNet copies of W7 Pro that I never used and were installed with out any modifications. I have only used the W7 Ultimate versions and didn't want to take a chance of losing there keys.
