Product Key history?
Did someone in TenForum mention a freeware program that could detect the Windows product key upgraded FROM? I thought I saw that a week or so ago but didn't note it then. Please don't reply with Keyfinder and Belarc Advisor. I am not asking about a program to view a current product key. There are plenty of those.
I am looking for one that displays the product key used for an upgrade to Windows 10. Not the Windows 10 product key.
