This has been a recent event and occurring more often. We manage windows updates using WSUS and automatic updates. Also, I have a custom script I will run that checks for any pending updates. Our automatic updates occur on Sundays and I run my script on
Monday or Tuesday. When I run my script against all of the hosts it shows no updates pending. Reporting looks like this:
[4:22:10 PM] - Checking local WU settings...
[4:22:10 PM] - Windows update agent is scheduled to run on every day at 3:00 AM
[4:22:10 PM] - Update Server: <WSUS URL>
[4:22:10 PM] - Target Group: CORP
[4:22:10 PM] - WUA mode Updates are downloaded automatically, and users are prompted to install.
[4:22:10 PM] - Instantiating Searcher
[4:22:50 PM] - This computer does not have any pending reboots (Pre-check).
[4:22:50 PM] - WUA mode: detect
[4:22:50 PM] - WU Server: <WSUS URL>
[4:22:50 PM] - Searching for missing or updates not yet applied...
[4:22:50 PM] - There are no further updates needed for your PC at this time.
[4:22:50 PM] - Windows Update VB Script finished
At this point I think everything is good. Now the next Sunday some servers will reboot outside of their maintenance window and WSUS shows that they installed a couple of pending updates. I use
the same script to manually install updates as well. The same script run against a machine that did not auto update suddenly says.

This happens despite no new updates being approved over that week. Also the updates that are pending are older and should have been installed long ago. KB2993651 seems to be involved in these incidents.
Any insights into what would cause a multiple day delay in reporting pending updates?
