[ RESOLVED ] Possible incompatibility issue with KB5017389 (Update for Windows 11 22H2)

Recommended Posts

Just leaving this as reference in case any users may have the same problem. I had an issue installing Windows Update KB5017389. I spent many hours diagnosing it and I was able to resolve my issue by uninstalling Malwarebytes. After that, I confirmed the solution on a second PC.



I'm on Windows 11 Pro x64 22H2 build 22621.521 and the update fails to install. It reboots 3 or 4 times. Update installation reaches 96% and then it starts reverting. Again taking 3 or 4 restarts to revert everything.

I tried manually downloading and installing the update from MS Update Catalog, but same error.
I'm running under the built-in Administrator account, with ZoneAlarm Free firewall v. and Malwarebytes Premium v.

I already tried:

  • Running the Windows Update troubleshooter
  • Running "DISM /Online /Cleanup-Image /RestoreHealth"
  • Running "sfc /scannow"

Update 2: I confirmed Malwarebytes being the culprit in my case. A second PC had the same issue and when I uninstalled Malwarebytes Premium first the issue was solved.


Please don't ask for logs. I'm not willing to provide them for privacy reasons. I solved my issue, but this thread may still hold value for users who have the same problem.

Please note there may be other reasons why KB5017389 fails to install. And I had a third PC that also has Malwarebytes Premium which does not have this problem.

The PC that had no problem installing KB5017389 with Malwarebytes had a clean install of Windows 11 22H2

The PC that have the problems both were updated from Windows 11 21H2 to Windows 11 22H2.


To the admins: In case this thread gets no replies within 7 days, It's probably an issue specific to my configurations. Feel free to lock this thread as I found my solution. But if more users run into this problem it may need a fix from either Microsoft or Malwarebytes.

For you and other readers....

If/when Malwarebytes is an issue, It does not have to be uninstalled just properly disabled.

First open Malwarebytes and turn off start with Windows.

Restart the computer and do the update again.
