Solved Will this work? (and how much work would it be?)

I am currently running 8.1 Core and want to use this windows 8 pro upgrade key to upgrade my windows installation. I have Windows 8.1 install disks, but not 8. Will this work? and does it matter if I intend to do a clean install or only an in-place upgrade?

I have only ever installed OS's via physical media, and I don't really know how these key-upgrades are supposed to work.

Also I am thinking about upgrading to 10 soon, and would rather go to 10 pro. My previous attempt to upgrade failed (via Winupdate and also using media creation tool), but I d/l'd a Win 10 iso and burned it to a DVD a few days ago. I am willing to give the upgrade a 2nd try, but I have been warned that doing a clean install of 8.1 might be the only way to upgrade for sure.

Anyone have thoughts regarding a fairly straightforward way of going from 8.1 core to 10 pro (I am willing to restore all my programs afterwards and backup all my data beforehand). I am willing to devote half-a-day, possibly more, this weekend towards accomplishing this.

This can also be done: Upgrade from Windows 8.1 to Windows 8.1 Pro with a Windows 8 Pro product key.

7. Do step 8 or 9 below depending on if you have already previously purchased a product key number or not. (see screenshot below)

​

8. If you Already Have a Product Key Number

A) Enter your product key number of the feature or edition that you purchased, wait for the key to be approved, click/tap on Next, and go to step 10 below. (see screenshot below)

   Note

You can use this option to do either of this below:

• Add the Windows Media Center feature to Windows 8 Pro or Windows 8.1 Pro.
• Upgrade from Windows 8 to Windows 8 Pro with a Windows 8 Pro product key.
• Upgrade from Windows 8.1 to Windows 8.1 Pro with a Windows 8.1 Pro product key.

I won't actually receive the upgrade key until some time this week, so probably next weekend will upgrade.

pro upgrade works as advertised, will attempt 10 upgrade some other day. Thanks for help.
