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?

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.

The Next button only becomes active when a key is entered. There is little tiny print "Skip this step" that can be clicked, though. Also, having the Windows 7 key is not enough - Windows 10 will not activate based on a key that it could find. It will activate based upon the original operating system activation. Important difference. The old operating system actually has to be installed and activated, Windows 10 will not read just a key stored in BIOS, for example. Once it activates from an upgrade, then future installs will activate based upon the information stored on Microsoft activation servers.
