Clean Install with Windows 8 Upgrade

    Windows 8 Pro




    I previously installed Win8 Pro from a disk that I bought from Staples. Today I installed 8.1 but I didn't do the clean install. If I would want to do a clean install, can I still do it by reinstalling 8 from the CD that I have and then go back to store and get 8.1 then do a clean install? I realize that with the clean install it will wipe out everything that I have and I will have to reinstall everything. If I went through all of that would there be any advantage?

    Hello Frank,

    Yes, that would be correct to do for a clean install for Windows 8.1 when you have Windows 8 Pro.

    It's still technically an upgrade though, but at least you would be starting from a blank slate. The only real advantage to doing it like this is if you didn't want to keep what you previously had, or if you had unrepairable issues in the old Windows 8 Pro installation.

    Hope this helps.

    Well, I haven't had any unrepairable issues. Actually everything is working very well, so I think I'll go by the, "If your car ain't broke, don't fix it."

    Oops, Shawn I had one of those senior moments when I told you that everything was running fine. I forgot that I have been getting the "Windows explorer has stopped working" pop ups. I have already posted it. One nice thing about being my age is that you can blame all of your mistakes on the "senior moment".

    Hello Ghost, and welcome to Eight Forums.

    If you have upgrade installation media for it and a 8.1 key, then you should be able to do so without installing 7/8 or first.

    I tried doing this with my retail upgrade to Win 8 Home.
    But during the installation when it asks be for the licence key it keeps rejecting it saying it is invalid.
    I successfully used it doing an upgrade over Windows 7 but I wanted a clean install.

    Hello Gilgamesh,

    If it's rejecting the product key that came with the Windows you purchased when 1st installing, then double check to make sure that you are entering it correctly. It's not hard to mistakenly enter 0 (zero) instead of O (letter), 1 (number) instead of l (letter), etc....
