Therein lies the issue. I've never questioned/delayed critical updates. (Yes, I have WU turned off, but I check it frequently-- at least every few days-- to make sure nothing new has cropped up. And I never miss a Patch Tuesday. I may be a curmudgeon, but I'm also an upstanding netizen.) In the last couple of years, though, Microsoft has become less and less transparent about what recommended/optional updates usually entail... they all just "resolve issues in Windows." The user has to actively seek out the information (outside of Windows Update) before installing if they truly want to know what is being updated.
I don't care for the way that they snuck the Windows 10 nag onto everyone's machine earlier this year, without notifying users as to what they were really installing. And I also don't care for the fact that they continue to try and push revised versions (along with other updates related to Windows 10) onto my machine even though I've actively hidden them.
If you don't want to upgrade your PC to Microsoft's latest (which I obviously don't want to do, and absolutely will not do unless they at least backpedal on forcing driver updates), then you can't just blindly install updates from Microsoft anymore. You have to scrutinize every single one that isn't marked "critical" to find out what it is... and most of them are related to the Windows 10 rollout of late.
I realize I am in the minority on this. But I'm stubborn and spiteful, and I will fight this to the bitter end.
