KB5043076 Marked as Installed on Windows 11, Yet Missing from Update History

Last week, Microsoft unveiled KB5043076 as part of the September 2024 Patch Tuesday updates for Windows 11. This update is mandatory, yet, similar to past Patch Tuesday updates, it comes with a range of issues.

Reports indicate that the Windows Update Standalone Installer may display KB5043076 as installed, but the update history may not reflect this, causing confusion among users.

Since the patch was released just last week, Microsoft has yet to address the concerns surrounding it. However, there are several potential fixes you can attempt to resolve the issue. To begin, ensure KB5043076 is installed on your Windows 11 system.

1. Run the Windows Update Troubleshooter

1. Navigate to Start > Settings > System > Troubleshoot > Other troubleshooters
   
2. Locate Windows Update > Run
   
3. Restart your device

After completing the restart, attempt to install KB5043076 on your Windows 11 system again by navigating to Start > Settings > Windows Update > Check for updates.

2. Fix Windows 11’s KB5043076 Using Run

1. Open Run, then type: services.msc
   
2. Find and select Background Intelligent Transfer Service
   
3. Click Start on the Status panel and then click OK.
   
4. If the status indicates Running, right-click it and select Restart.

Scroll to find Windows Update in the service list and repeat the same steps as above.

3. Perform an SFC and DISM Scan

1. Launch Command Prompt with administrative rights.
   
2. Input: DISM.exe /Online /Cleanup-image /Restorehealth
   
3. Allow the scan to complete.
4. Next, type: sfc /scannow
   

After the process (which may take 10-30 minutes depending on your device), restart your PC and try to download and install KB5043076 on your Windows 11 device once more.

4. Install KB5043076 on Windows 11 by Resetting the Windows Update Components

You can also consider resetting the Windows Update Components, though this method is more complex and requires a certain level of technical expertise. If you wish to proceed, refer to our detailed guide.

Windows update continues prompting me to install the 2024-09 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5043076). I’ve attempted installation three times, and every time I receive the “something didn’t go as planned”message. I then went to the Windows Update Standalone Installer to run the update, but it indicates that it is already installed on the system, which it isn’t (it’s not visible in the update history). How can I rectify this?
