“...Didn’t realize it still had that kind of footprint....”
There were a lot of folks, and businesses, that originally upgraded to WIN8/10 when they came out, and then found themselves switching right back to WIN7. My wife’s business did that.
IMHO, Windows 7 was by far the best platform they’ve ever produced. Like some others here, I tend to lean more toward iOS and/or Linux, but I do keep a WIN10 laptop handy as well.
But yeah....there’s a whole. bunch of WIN7 users out there that swear by it, and they’re not happy that Microsoft wants to kill WIN7.
I'm one of them. I have several expensive programs that won't run on Windows 10.
