Both my Desktop and Laptop are suffering the same problem when attempting to run the Windows Update Troubleshooter. Operating system is Windows 11 24H2 with all updates applied to 11 December 2024 including KB5048667. After going through to the point where the troubleshooter runs, I get "I'm sorry.  I was unable to run the Windows Update diagnostic. I might need to transfer you to an agent to help solve your problem." I've done all the obvious (sfc, DISM) and no problems were found. I'm thinking it must be a generic problem as it happens on both my Windows 11 machines.

    Because it's a stand alone update (automatic) those 2 don`t apply.

    I resolved the problem by using the following;

    https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/caa3ff4a-6420-4341-aeae-33b2d7f463be/public/windows11.0-kb5027397-x64_3a9c368e239bb928c32a790cf1663338d2cad472.msu

    KB5027397 is the 23H2 enablement package, which has nothing to do with the KB5050009 24H2 update error Lee Relph was facing.

    Woo! Success! Finally, it installed then I had to restart my PC which took abut 30 minutes to update. My OS build number is now 26100.2894. Is that up to date now?

    Thanks again for your help with this! Appreciate it! :-)

    Glad to hear that. 👍

    Yes, 26100.2894 is the latest quality update.

    It says 26100.2605...

    EDIT - the download has suddenly changed to install and is at 17%...

    I hope it worked eventually.
