have had no updates since 2014
My 2011 HP desktop on W7 has been equally reliable, my wife's was even older so we replaced it last year. The fussy, over-complicated W10 confirms that 48% of users are right to stay on W7 especially when we have no need of fancy gimmicks, still less of Microsoft watching our every move.
However, the W7 updates still arrive few months and all are security related. My auto-update mysteriously turned itself off about 2015 and maybe yours has done the same. I don't bother with all the hype but these security updates are essential especially if, like most people, you trust the internet for banking & finances
