Generic comments from a guy who's day job is to try to train people how to fix broken, mostly Windows, computers.
1. If a computer runs Windows 7 it has the hardware power to run Windows 10 just as well. Fact.
2. Windows 7 is no longer suitable for safe internet use. Can't be made safe. Mostly fact, a little opinion. More fact is that Microsoft has stopped doing security updates for Windows 7, and will do that for Windows 8 eventually (if there are any Win8 users still on the planet). This makes using them in the future pretty darn problematic.
3. Windows 10 is still available as a free upgrade. Microsoft just doesn't want to make it too widely known. Details from a very respectable voice, Ed Bott, sorta' the MacVanP of Windows.

4. Everyone backup your junk right now! External hard drives are cheap. Get two. Alternate them. Belt & Suspenders? Check! Advice. If you've never done it or don't know how shoot me a PM.
