I upgraded my PC from Windows 8 to 10 while it was free. I had to wipe HDD, and now I'm back to 8. How do I get back to 10?

I recently had to wipe my hard drive running Windows 10 due to an issue. I reinstalled Windows using my OEM CD of Windows 8. How can I reupgrade to Windows 10 again?

download the Windows 10 media creation tool and use it to make a win 10 installer on USB, or upgrade current install.

I think the upgrade option is still there, if it isn't I would use USB to fresh install win 10

it should reactivate since you had 10 on PC already
