Windows 10: Win 10 Pro upgrade from Win 10 Home

Just realized that I bought a Win10 Pro upgrade (from Win 10 Home) at the MS Store on 01/13/17, but never installed it! I have the order number but I don't think I ever got a Product Key. How can I install the update so I can get Pro and use Bit Locker? Thanks.

Win 10 Home to Pro upgrade

How do I upgrade from Win 10 Home to Win 10 Pro with a digital Licence. The in structions say

• If you have a digital license for Windows 10 Pro, and Windows 10 Home is currently activated on your device, select
  Go to Microsoft Store and you'll be prompted to upgrade to Windows 10 Pro for free.
  

Fine, but how do I get a digital Licence for Win 10 PRo??

Going to Microsoft Store via the upgrade with digital licence link, provides no opton for upgrading.

Any solution??

 

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?

 

Trying to upgrade to Win 10 Pro

I have Win 10 Home on my Lenovo laptop. I bought a Win 10 Pro For OEM software pack to upgrade to Win 10 Pro but my system didn’t accept the 25 character prod key. What should I do?

I’m trying to install the upgrade via DVD (which came with the pack) but I noticed it said during the process that it would install Win 10 Home on my laptop but I already have that. Any suggestions ?
