I hope they change their mind before tomorrow and continue support for Windows 7!
I doubt it very much, Tom, MS has been trying to get everyone off earlier editions and to update to Win 10. There are still ways people on Win 7 can update for free, not that MS advertises it. For mine, it's a sneaky way to promote Win 10 installations, by unofficially leaking ways to freely update to 10.
Apparently, the folk over at majorgeeks successfully updated to and activated Win 10just by installing it over Win 7 and using 7's product key. Haven't tried it out myself, but then I haven't the need to.
