Important Updates Disappear?

I have my PC set to Notify me of Important Updates, but not download or install them.

On at least 2 different occasions over the past 2 months I seen maybe 17 -19 Important Updates shown when I open Updates, but chose not to install them at that moment because I was doing other things. When I went back a few days later they where all gone. This happened this week, as well as about a month ago. And, they were not automatically installed either.

What's going on with these disappearing Important Updates? Unfortunately I never checked to see if they were somehow redundant because I think they would disappear.

Two days ago, I had 27 important updates which I had not installed.

Yesterday, my computer was up to date! Not a single update.

So I checked for updates for hours but had to stop since it was eating cpu and not come up with any results.

Try searching and post whether your search ended successfully without any updates, or was just stuck for hours.

Mine was stuck so I followed this procedure and found the old and newer July updates in minutes.


Set Windows to Never check for updates.

Make sure wuauserv is not running in the background eating your CPU . If it does, just stop the service.

Download and install KB3168965.

Restart and set Windows to Check for updates but let me choose what to install.

Click search for updates.

Let it search for 1-2 hours. Should come up with results.

I used to have that setting, so as to control.
But it do have disadvantages more.

Do change your setting "Install updates automatically (recommended)"
As for Date "Every day" and Time "important"
Do note that the Time you select is when the PC is running, &or while using.
The standard day/time is because Microsoft assumed that all PC(s) are running 24/7 (24 hours 7 days).
Make sure that your selection on the timing is when you are using your PC.
--The reason is that if you have turn off the PC during that period of time, updates may not check by itself.

As for these setting;
(1) Recommended updates (2) Who can install this updates; ensure these 2 have a tick mark on the box.
As for Microsoft Updates --unless you are using Microsoft products, which i do not, but still leave a tick mark.
The last option --Software notification-- also an option (i leave a blank).

I do not do it manual, as the setting take care of everything.
Do note on the date/time, which the PC should be turn on.

When i do Shutdown, if the updates are downloaded, it will say the "Updates before Shutdown"
Do it, even if you are just want to restart /reboot.

Just a few days ago, the PC stated to do updates.
After shutdown and then turn on, there are 20K++ settings are updating, for just a few minutes.
After complete, i do a shutdown and then turn on.
This is to ensure everything are in normal, plus for safety reason, i did a create a restore point, just in case.

Final note: Ensure your internet connection is active.

I have just opened Updates again and there now are 10 important updates reappearing.
I'll install and keep track
