I upgraded to Windows 10 from my Windows 8.1 (Windows 8 originally). My 30 days in which I could roll-back are over, but I want to comeback to Windows 8 since Windows 10 is causing problems.
I can download an ISO of Windows 8 using media creation tool, then burn it onto a DVD/CD. My Windows 8 key is an OEM version so the product key is tied to the motherboard.
Can I install Windows 8 and it will activate? Or did the product key get consumed by Windows 10 and I have to stay with it?
