True, but I'm sure there are a lot of cases where the OS wasn't updated because of the necessary investment to jump to a new Windows version.
There are very few free/open-source operating systems that get security patches for as long as Windows does. Major versions of OpenBSD are only supported for 5-6 years. Most Linux distributions only get 3-5 years. Red Hat promises 10 years of support, the same as Windows 7/8/10. None comes close to the 13 years that Windows XP was supported for. So you're gonna have to update anyway, at roughly the same interval if n…
I thought that security updates are only made for -current, the current stable release, and the previous stable release. So, 1 year of support, not 5-6.
A cursory look at the errata seems to confirm this.
