Upgrade a Win 10 home OEM to Win 10 Pro OEM with Win 10 Pro OEM Key?

I recently purchased a laptop that has an OEM version of Win 10 Home on it.

I verified this by using : slmgr -dli.

Previously I had purchased an OEM Win 10 Pro Key.

Can I use this OEM Win 10 Pro Key to upgrade the OEM Win 10 Home to the OEM Win 10 Pro.

If so what are the steps to accomplish this?

In addition, I assume that is this is possible, that the current product key will be updated to the new product key?

The reason I am asking this is that it's my understanding that these product keys are tied to the bios on a name brand laptop.

TIA

 

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?

 

Windows 10 and 7 Pro OEM activation

Hi,

From what I understand the Win 10 Pro OEM key can be used to activate Win 7 Pro OEM. Bascially I have a request to build a PC with Win 7 Pro, as this is need for the software used by the business. I have run out of copies
of Win 7 Pro OEM.

I've tried using a Win 10 Pro OEM key for a Win 7 Pro OEM activation, but it's not working, tells me the key is not valid. Am I suppose to install Win 10 pro OEM, activate it, and then install Win 7 pro OEM, and activate
with the same key. I'm still getting orders for PCs with Win 7 Pro, and finally run out of copies.

What is the correct procedure to activate an Win 7 Pro OEM install with a Win 10 Pro OEM key?

Thanks
