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)?
