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?

    Please open admin Command Prompt and run:

    net start wuauserv

    Do you get any errors?

    Entering that command gave this odd response:

    "The requested service has already been started.

    More help is available by typing NET HELPMSG 2182."

    I entered that command and again it said "The requested service has already been started."

    ???

    Thanks for the update. Windows Update is starting correctly.

    0x800705b4 is a time-out error. Maybe resetting WU using this batch file will help. https://www.elevenforum.com/t/reset-windows-update-in-windows-11.3808/

    Hi Ramesh Srinivasan,

    I have the same problem as LeeRelph, except that my error code is 0x800706be. When I run net start wuauserv, Windows update service starts normally, then the update KB5050009 starts to download, but then stops and I still get that error code:

    Any suggestions or links for this one? Thank you!
