KB915597 - Update for Windows Defender not installing.
I'm using WSUS 3 in a network. Most of the clients report that KB915597 - Update for Windows Defender is downloaded, but not installed.
In the local Windows Update log, it has shown since it's approval that this update is installed every time AU is set to install updates, but when the client system goes to sync updates the next time, it downloads it again and installs it again. Over & over & over. Other updates are installing & aren't stuck in this loop. I also believe this update is having the same problem on other networks I manage.
should I simply unapproved this update & forget about it? Or is there a way to get this update truly installed & finished for good.
I have a GPO that sets all clients to install downloaded updates automaticly & reboot if needed at 17:00 every day, so it's not a "needing to reboot" issue.
Thanks for your help

The answer to your question is in the event id(s) on the clients and/or the error code generated by the installation. Try running it manually on one of the clients to see what code it generates.

it could also be that this update got corrupt on your wsus server.
so then run on your server the command:(located in %drive%\Program Files\Update Services\Tools)
wsusutil reset
This Checks that every update metadata row in the database has corresponding update files stored in the file system. If update files are missing or have been corrupted, WSUS downloads the update files again.
