Windows 10: How do I do fresh install of Windows 10 with Windows 7/8.1 product key

Hi! New to the forum from Indiana. Will be building a new computer very soon, and will be switching from Windows 7. Currently running an Asus M5A99X Evo R2.0 with an AMD FX4350 Black Edition, and will be upgrading to an Asus ROG Strix X470 F with an AMD Ryzen5 2600 or 2600X.

I saw where you can download a copy of Windows 10 using the media creation tool, and activate it using a Win7 or Win 8.1 product key. If you do this, do you still have to pay for the software? Also, if you activate using one of the other product keys, and you have to go back to the older software for some reason (Windows 10 doesn't work out or something like that), can you still reuse the key for the original version (go back to older version)?

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

Now that I have finally upgraded from Windows 8 to Windows 10 will my Windows 8 key work with a fresh install of Windows 10?

You need to upgrade the first time around. Once you upgrade, you can use that key for a clean installation. I've done 2 clean installations with my Windows 7 key since I upgraded to 10 the first time around.
