I guess being lazy that I have not switched OS but if MS has no security for Win 7 then I have no need to keep their OS. Know I have at least one Linux system on a USB drive here - may be a couple years old so need to refresh. Need a kick in the butt - maybe for my 70th birthday in a couple of weeks. Of course its the worry that a couple legacy programs will not work on a new OS. Just don't need any issues right now.
