Windows 10: Activation problem with Win 10 Pro 0xC004C003

Hello,


I built my new PC and wanted to move the digital key from my old PC to new one. But for some reason the activation doesn't work. The troubleshooter doesn't help either. I don't know what to do anymore, please help.

Win 10 Pro upgrade using Win 8 Pro product key

I just bought a new computer running Win 10 Home. When I went to upgrade to Win 10 Pro using my Win 8 Pro product key from my old computer, the upgrade wouldn't activate.

Now I'm stuck with a bunch of error messages (mainly 0xC004C003) and am being told windows isn't activated. I can't seem to get my activated Win 10 Home back.

I don't have a product key for the Win 10 Home because it came pre-installed. There's no product code recorded on the packaging or labelling on the device.

So:

How do I either

• activate the Win Pro upgrade, or
• Get my activated Win 10 home back?
