Your device is missing important updates. Win 10. Suddenly?

Question

Windows

How much I use ten (literally from the moment of release), I see this for the first time. I generally prifigel, the eye itself was hooked, seeing something new in the tray.
I have updates turned off. Assembly 1903 (or 1809) or some such, antediluvian, on which there is not even x box life (which was needed for games), because it is not installed, because Windows needs to be updated, which does not occur due to the old assembly.

a week ago, I would have poked and updated, seeing what they offer. But now such times that I decided to perebzdet. I repeat: updates are disabled, there were no such notifications before, I did not know that such an icon existed at all. Why, under such conditions, does an icon that I have never seen before appear and updates that have not been seen for years?
Maybe paranoia
