Windows Update Troubleshooter failing to run, anyone else having problems?

I had the same problem. The 24H2 update and the microsoft.net update were just stalling and troubleshooter didn't even open properly let alone scan. I think it was these failed updates that were stopping the troubleshooter working. I tried all the above for half a day and nothing worked.

In the end I resorted to Windows XP experiences and I downloaded both downloads (search for the KB number) manually from the good old microsoft update catalog. Make sure you get the exact correct one. Check the description in your settings and match it to the different ones in the catalog. You setup automatically knows which version it wants.

Then I went into services and stopped the update service. Then started it.

copied the downloaded files to my desktop. the 24H2 one need unzipping first.

Then from my desktop I double clicked the downloaded updates and let them run. Both took a long time but both worked.

Windows update in settings still said "error" but another trick there is to pause updates for a week or 2.............and then click resume updates at the top and VOILA "WINDOWS IS UP TO DATE!"

And guess what. Windows troubleshooter is working. A bit uselsess if the troubleshooter won't work because of the error lol but hey ho.

The above from when I decided just to manually do it took about 2 hours total.

agree, support isnt support. its KMA and goodbye

same issue here

Totally agree. Clumsy, unhelpful "advice" from Microsoft.

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.
