Windows 10: Upgraded to Win 10 Pro, but laptop needs repairs

With several hours of troubleshooting with no home remedy to my laptop issue, I may have to return the laptop not even 1 month of use. Can I refund the Windows 10 Upgrade I just did to this laptop? Or can I reuse the license when I get the new laptop, and upgrade the OS again?

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 ?

 

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??

 

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
