It will be interesting to see if the product key works Donny. I doubt it will. In my case I was in the middle of transferring all my stuff from my old Win 7 machine to the system in my sig that originally was also Win 7. My original plan was to do the free upgrade to Win 10 on the old box last July, test it, make sure everything worked then do the same with the new box. That's when I discovered I also had an invalid key and it wouldn't do the upgrade. I was all over the internet and talked to several people and there's no way to get a valid key any more. At least that's what I've read and was told.

I suspect your only option is to buy and install Win 10 but don't worry, it works fine and there's no problem at all working with it. If you really do find a valid key and can reinstall Win 7 please let us know because I still have that old box and would like to do that with it. Like your's it too was finally running so slow and messed up there's nothing to do but a reinstall. If I want to use it I may have to buy and put Win 10 on that one too.
