Windows 10: [Solved] Transfer Windows 10 Pro to already activated laptop on Windows 10 Home

I have 2 devices: one is with Windows 10 Pro digital license and another one is with Windows 10 Home digital license. I know that I can deactivate Windows using slmgr /upk. Afterwards, if I click on troubleshoot link in settings it restores my old product key.

What I want is to swap Windows edition on these devices. Is there a way to do this without formatting the device? Both my devices have retail keys.


PS: Issue is solved. For those who will face same problem. I used Produkey software from NirSoft to get the product keys from both my devices. Then clicked on "Change product key" to upgrade from Windows 10 Home to Pro. Personally I had to click on "Change product key" twice, as first time it showed as unactivated Enterprise Edition and second time it successfully activated Professional Edition.

Windows 10 Activation (Insider)

I bought Windows 7 Pro OEM key from G2Play.net for 12€ to upgrade to Windows 10 Pro - worked like a charm but be advised if you buy a OEM key you can not download the Win 7 iso from microsoft and have to get it elsewhere.

 

Windows 10 pro

I need to change my motherboard, have windows 10 pro. When i google how to it says go to activation then add an account, my issue is there is no add an account option under activation? Or am I in the wrong window?



Not sure how to proceed, ive googled it and the same results. Do I have an OEM or? On the disk sleave it says OEI DVD?
The COA says windows 10 pro for OEM software

 

Windows 10 Activation (Insider)

How long did you wait for activation?
When I re-installed with a fresh install... it took a few hours to sync and activate.
However, it did, finally, activate.
