    cant run windows 8.1 setup


    i have had windows 10 installed on m,y pc since july 30ish....and ever since i upgraded to windows 10 from 8.1 the pc has been locking up every time i try to do anything...something as simple as opening my documents causes the pc to use 100% disk too the point i have to reset......i was hoping i could install windows 8.1 since i still have the key by using the upgrade assistant but when i tried to run it it said "this system is unsupported"
    and i have tried everything i could think of to fix the 100% disk issue nothing has worked
    any ideas would be greatly appreciated

    Hello War91, and welcome to Ten Forums.

    You should be able to do a clean install of Windows 8.1 at boot.

    You can purchase a USB drive for next to nothing in many retail 'bricks and mortar' stores. You only require a small 4-8GB drive and it is dead cheap.

    Since you upgraded to Windows 10 from 8.1, you could also try to go back to 8.1 if it hasn't been more than 31 days, and you didn't delete the Windows.old folder.
