Windows 10: Can i enter a win 10 Home product key on win 10 PRO?

Can i enter a win 10 Home product key on win 10 PRO? When I got done building my pc I chose win 10 pro and then selected “I don’t have a product key”. But can I still enter my win 10 home product key on my win 10 pro system?

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?

 

Why was I not asked for a product key when upgrading to Win 10?

According to your spec you have Win 10 Pro, but perhaps that doesn't reflect your PC.

You haven't stated which edition of Win 10 you have on this machine, nor what your Win 10 key is for.

For example, if you already have Win 10 Pro and your key is Win 10 Home, that would be a retrograde step.

Win 10 Pro product key not accepted

I purchased a new laptop with Win 10 Home digital license. At the same time I purchased a Win 10 Pro update disk. When I try to change product key under Activation, the product key is not accepted. "The product key you entered didn't work".
