Windows 10: Possible switching Win 10 licenses?

I had A PC running a free upgrade Win 10 Pro, but had to replace the mother board.
The "new" mother board was actually used, with Win 10 Home linked.
I linked them both to my Microsoft account, and yet Windows would not activate, complaining that the license is for Home.
Troubleshooter > I changed hardware, only lets me choose that I am using the old motherboard.
I have no keys.
Is there a way to get my Win Pro activated?

Thanks!

That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.

 

Windows 10 upgrade license

The interesting question is that: the upgrade takes place before 29 of July. If I upgrade the PC (change the MB), and I transfer the Win 8.1 license to this new PC (cause 8.1 is retail FPP), will I be able to upgrade to Windows 10 for free? Or a upgrade license must be bought?

 

How to move Win 7 license over to a new rig?

AFAIK, OEM licenses will have a Product ID that usually contain "OEM" within it - it can be found under Control Panel > System > Windows Activation (usually).
