Win10 Home to W10 Pro Upgrade Error using Product Key

The keys are there because 1. It is the product key you end up with when you gain a digital license for Windows 10 Pro through legitimate means and 2. When you do a clean install of Windows 10 (without adding an ei.cfg file), on a computer with a product key for Windows 10 Home stored in UEFI, you can use the generic product key to upgrade the Windows 10 Home that installs by default to Windows 10 Pro - but only if you have an existing digital license for that computer for Windows 10 Pro previously stored on Microsoft Activation Servers.

The reason the generic Windows10 Pro product key will not upgrade your Windows 10 Home to Pro is because you do not have a preexisting digital license for Pro for that computer stored on Microsoft activation servers.

 

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.
