Win7 has less than a year of life left.
I was one that was holding onto Win7 as long as I could. A hard drive crash, gave me the opportunity for a clean install, and decided to give Win10 a shot. There are some differences, and some annoyances, but overall, I like it. Things seem to be way too "dumbed down" for any IT professionals, but I guess it's more for casual users than IT Pros.
Overall, I don't miss Win7 at all.
