I'm staying on 7. Windows 10 is unusable and honestly Microsoft should be embarassed by releasing something so terrible as their flagship project.
You don't really need Microsoft updates, just buy a quality anti virus software platform and that will cover you. 99% of virus and malware infestations come from users not following safe computing practices anyway (clicking on rouge links, accepting downloads they shouldn't, etc), you don't really need them. I used Windows XP well after support was dropped and never had an issue.
If I ever HAVE to get off the OS I'm going to Linux. I will never use Windows 10 unless they do a MAJOR UI overhaul
