The big updates most people are familiar with come out on “Patch Tuesday,” the second Tuesday of the month. But almost none of these people even realize they’re signing up to be “seekers.” “B” Updates: Patch Tuesday Microsoft tricks people it calls “seekers” into installing updates before they’re fully tested.
That’s all great, but the way Microsoft handles C and D updates is just bizarre. You don’t have to install updates one by one and reboot in between each. Quality updates are cumulative, which means they contain all the fixes from previous updates. So, when you install the December cumulative update, you get the new security fixes from December as well as everything that was in the November and October updates, even if you haven’t installed those previous updates.Īnd, if you’re updating a new PC, you only have one big cumulative update package to install. This distinguishes them from the big “feature updates” like the October 2018 Update and 19H1 that are released once every six months, usually in the Spring and Fall.
Microsoft calls these “quality updates,” and each is released once per month.
