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.

    This is happening to me too. My PC is only 8 weeks old.

    The problem started when my PC couldn't install the latest KB5050009 update and kept giving the error code 0x800705b4. I tried running the troubleshooter and got the same message as everyone else - that it couldn't run the diagnostics. I have also tried other wrokaround as suggested here and online but none of the work

    With so many people experiencing this, is it not fair to assume the new Windows update is the cause rather than our systems? More to the point will this have a drastic effect on our systems going forward if we can't get the updates or get the troubleshooter fixed?

    Hello William Y,

    This is the third time your most recent Windows update has knocked out sound on my HP Tablet. It doesn't happen on laptop, just the tablet. Twice I've had to grant control of my tablet and allow a Microsoft technician to correct the problem, and here we are again.

    Is that my option again? Seems like this should repair itself..........

    Thanks for help here. Photobarb837

    The trouble shooter worked for me? My updates are working again.

    I can not update the 23H2 this is the statement that it says about the computer 2025-01 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5050021) it also says download error - 0x80040154

    0x80040154 occurs if there is a mismatch between the servicing modules and the references in the registry. Also, DISM and SFC won't run, as far as I know.

    I can help you if you start a new thread and post the link to that thread here.
