I recently upgraded two Windows 7 PCs to Windows 10. I then went to put in my recently purchased Windows 10 Retail software key code and it wouldn't allow me to change it. It said (paraphrasing) "Windows has been activated with a digital license and cannot be changed". So, I'm wondering if these Windows 7 machines got the free upgrade registered way back when Windows 10 was free. But how can I tell for sure if this is what happened?
