2024-01 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5034123) won't install.  Ran troubleshooter, scannow /f etc. and nothing works.  Any ideas?

See if manually installing the standalone update from the Microsoft Update catalog works.

This notice gives you the link to the download from the Microsoft Update catalog.

January 9, 2024—KB5034123 (OS Builds 22621.3007 and 22631.3007) - Microsoft Support

If that doesn't work either, what I have done in the past is to run the Microsoft Hide Window Update utility that I zipped up and attached below.

Unzip and run the utility.  It will find the KB5034123 update that won't install.

Check the box to hide the update.  The utility will run again and report that the problem is 'Fixed.'

Close out of the utility, restart the PC and then go back to Windows update and keep clicking on the Retry button if necessary to clear out the uninstalled update.

Next month's cumulative update will include the files from KB5034123, so you won't be missing them if February's installs without incident.
