Windows 10: Can I go back and just do a clean install

I originally followed the path to upgrade my 8.1 Pro to Windows 10. Everything went fine and I created the USB during the process. Activation was OK.
Then after a few days and some unusual problems I reloaded my last Image of 8.1 Pro.
Question is Can I go back and just do a clean install since I have already did the upgrade process?
Or do a upgrade again?

Can I do a clean install? (I upgraded)

Yes, you can perform a direct clean install. You have several methods of performing a clean install.

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft Activation
Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate.

So, there is no need to know or get a product key, if you need to reinstall Windows 10, you can use your Windows 7 or Windows 8 product key or use the reset function in Windows 10.

If you are prompted to enter a product key, click 'I don't have a key' and 'Do this later'

No need to go to 8 if the system with 10 is already activated.

Download the ISO or prepare the USB drive using Media creation tool:

Hello Shipinomore,

Yes you can clean install Windows 10 Pro since you upgraded to the free Windows 10 Pro on your activated Windows 8.1 Pro PC to register that PC for the Windows 10 Pro activation. *Smile
