Windows10 requiring product key


Is your Windows 7 activated? If it is properly activated a Windows 10 upgrade should not ask for a product key.

Have you tried the "Upgrade this PC now" option of the Windows 10 Media Creation Tool?
Windows 10

After you get a successful upgrade, and the Windows 10 is activated, then you can do a clean install by booting from a Windows 10 USB or DVD which you can also make with the Media Creation Tool. A clean install will ask for a product key and you click on the tiny text that says Skip the step. Might have to skip the Product Key two or three times. IF the upgraded Windows 10 on the same computer was activated, the clean install of Windows 10 will activate. And remember - you have to stay with either the Home or the Pro version - you can't go from Home to Pro or from Pro to Home.

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.
