I preferred Windows 7 and would go back to it if I had to buy a new computer. But (as has been noted already) Support for it will dry up soon. You mentioned that you’re like me and a bit unknowledgeable about the finer points of computers, but if you do want W-7 then learn to turn off the automatic updates.
BTW, my local Office Depot will sell a copy of W-7 and you’ll never need to deal with Microsoft again. I haven’t asked, but I’m sure they’ll install it and turn off the updates too.
I haven't heard of that before. What is the purpose?
