Windows 10: Windows Update Troubleshooter failing to run, anyone else having problems?

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.

Windows Updates failed to instal

I'm not sure how differant XP media center Edition is but you could clear the history \ cache if these folders are there.

Step 1 Register DLL files.

=================

By trying this step, we can check if the update engines are working properly.



1. Close all instances of Internet Explorer.

2. Click Start and Run, type "Regsvr32 atl.dll" (without quotes) in the Open box and click OK.



Note: There is a space between regsvr32 and atl.dll



3. Similarly, one by one, register the files listed below:



Regsvr32 msxml3.dll

Regsvr32 wuapi.dll

Regsvr32 wuaueng.dll

Regsvr32 wuaueng1.dll

Regsvr32 wups2.dll

Regsvr32 wucltui.dll

Regsvr32 wups.dll

Regsvr32 wuweb.dll

Regsvr32 qmgr.dll

Regsvr32 qmgrprxy.dll

Regsvr32 jscript.dll



Note: If you encounter errors while registering any of these files then skip that file and continue with the next one.



If the issue persists, let's move on to the steps below to verify Windows Update services and temporary folders.



Step 2 Verify the relevant Windows Update services.

=========================================

1. Click Start->Run, type "services.msc" (without quotation marks) in the open box and click OK.

2. Double click the service "Automatic Updates".

3. Click on the Log On tab, please ensure the option "Local System account" is selected and the option "Allow service to interact with desktop" is unchecked.

4. Check if this service has been enabled on the listed Hardware Profile. If not, please click the Enable button to enable it.

5. Click on the tab "General "; make sure the "Startup Type" is "Automatic" or "Manual". Then please click the button "Stop" under "Service Status" to stop the service.

6. Then please click the button "Start" under "Service Status" to start the service.

7. Please repeat the above steps with the other services:



Background Intelligent Transfer Service

Event Log

Remote Procedure Call (RPC)



Note: Event log service is enabled on all of the hardware profiles; this service does not have an option to enable or disable on certain hardware profile.



If it still does not help, let's proceed to step 3.



Step 3 Reload the Update temporary folders.

===================================

One possible cause is that the temporary folder for Windows Update is containing corrupted files. Let's erase all the files there to get the system clean.



1. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net stop WuAuServ



2. Click Start, Run, type: %windir% and press Enter.

3. In the opened folder, rename the folder SoftwareDistribution to Sdold.

4. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net start WuAuServ



Please test the Windows Update website and let me know the result. If the issue persists, to clarify the issue and provide more accurate troubleshooting steps, please assist me in collecting the following information.

 

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.

 

Windows Updates failed to instal

I just did step one and they have just all installed.... thank you so much.... it was quite frustrating having that update window pop up every 5 minutes and failing to instal every time

Thanks mate
