First, there are ways to find your Windows product key. I did it on my wife’s Windows 10 PC with factory installed software from watching a youtube video. It took a little while, but it worked first time. Here’s the Windows 10 video I used: https://www.youtube.com/watch?v=uqJbsvIytyM

Why not buy yourself a Windows 7 license, or maybe upgrade to Windows 10? They start around $2 for 7. I suggest you go with a seller with a verified history of delivering licenses.

Thanks, everyone.
After messing with it all day, found out MS Office is a goner and no other choice but to download Open Office. The good thing is all the documents are there in Open Office so nothing lost.
A quick consult with the computer shop guy verified what some of us felt about just not bothering with any further updates on 7. And that most everyone he sees can’t stand 10.
