Windows 10: Win 11 Pro Upgrade - Not Working - Bought TWICE

I bought Win 11 Pro Upgrade using MS Store. After Clicking on BUY the dialogue dissapeared - so I thought it did not work - as there was no information saying "Thank You"...SO I chnanged the credid card and tried again. But again the same. Then I saw that the Activation in Settings now showed a button "Install" - they RENAMED the Button from "BUY" to "INSTALL" - Wow no red color no flashing green light...Then I checked my MS account and found that they actually charged me twice for exactly the same Surface Pro 8 for the upgrade from Home to Pro.Then I clicked the button in activation to instal

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 ?
