Windows 10: Upgrade Window 10 Home digital license with Windows 10 Pro product key

When trying to upgrade from windows 10 home to windows 10 pro we are getting this error 0xc004f050. The original license is a digital license and the upgrade we are trying to perform is a purchased license key.

Windows 10 upgrade license

Hello guys,

I have 1 license of WIndows 8.1 FPP/retail license. I want to upgrade to WIndows 10, but I one thing is unclear to me.
If I upgrade, will WIndows 10 license be retail or it will "turn" into some sort of OEM license?

I ask this because I upgrade my PC, you know, more memory, replace HDD, and I intend to upgrade the MB and CPU to Kaby Lake platform sometime in the future, (and of course sell the replaced hardware)
This thing is not clearly mentioned anywhere.

Thank you.

I read through most of that thread and it seems you have to jump through windows insider hoops. Is there a Retail Windows 10 x64 PRO ISO I can download directly from microsoft that my windows 8 key will work with?

 

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?
