I don't recall having it as a plugin, but it WAS nearly a decade ago (man, where did the time go?). I definitely recall using the windizupdate site and having checkboxes next to each item if I wanted to update through it. Maybe the plugin was needed for the site to work. Anyways, that was a thing I did. I don't remember how/if this relates to anything that was being discussed anymore. Plus windiz apparently doesn't work anymore, so I guess it'd be moot, anyways.
Also, to hell with Windows and their update policies. I was dual-booting my laptop with Windows and I recall specifically setting it to NOT do ANY automatic updates. And then one day I needed to quickly boot into it for something and the ****er updated on me. I was between classes at the time the update decided it was gonna go through. 45 minutes later, still updating, I had to go to class, so I just left the laptop in the computer lab to keep updating against my will. Came back from class hours later and the thing was STILL updating. Microsoft, you are the devil.
