When are updates REALLY installed

margrave55 · 20 Apr 2018

I see that these updates were installed on my desktop on April 10:
KB4093112
KB4093110
KB4018355
KB4018354
KB4011717
KB4018353
I took that from the "view installed update history" screen, which shows no "newer" updates.

When I did a shutdown/restart yesterday April 19 it installed some updates.
I presume that this was the set of six updates listed above.

So why does the update history show "successfully installed on 4/10/2018" if, in fact, they were installed on 4/19/2018?

Should I take it that the April 10 "installed" date was the date they were downloaded ... and that they were not "really" installed until I rebooted on April 19 ?

Margrave,

Look in Event viewer - see my guide in this other thread.

You are indeed correct. A lot of updates are installed upon a Restart. This has been the case way back to Windows XP, if not before.

I always do a Restart to make sure of updates being done in a timely manner.

You can investigate further if you wish, the MS info is very approximate.

Reliability Monitor also shows updates, and I generally find its GUI a little easier and less labor-intensive to navigate than Event Viewer. Just my opinion, though: either one works fine.
Here's what update info looks like in relimon:
