Why did this happen?

Windows updates usually fail because of either device or internet failure during the update installation process. However, other reasons include:

  • Improper installation. 
  • Malware or virus infection. 
  • Storage errors. 

How to fix this?

Here are 10 fixes you can try out. 

Restart your PC

Restarting your PC is by far one of the most simple and effective solutions to just about any problem you run into while using Windows. Graphics issues, network problems, update glitches, rebooting has got you covered.

It’s also not a bad idea to check your internet connection real quick. At times a dead or inactive internet connection can be the root cause of a lot of problems.


Disable VPNs

Improperly configured VPNs can cause conflicts with network adaptors on Windows, whether you’ve set them up manually or using a VPN client that does all the work for you.

In any case, try disabling the VPN and reverting any changes to see if your VPN conflicted with the Windows update.


Disable any third-party antivirus

Microsoft has revealed that certain Symantec and Norton antivirus versions do not work well with this particular update. Try disabling or uninstalling any third-party security software that you might have on your PC to see if you can install the update then.


Run the Windows 11 update troubleshooter

Just like Windows 10, Windows 11 also comes with a bunch of helpful troubleshooters that’ll automatically detect and resolve any problems your PC might be facing. The same goes for the update troubleshooter, here’s how. 

Step 1: Press the Windows key and search for Troubleshoot settings. Click the corresponding search result. 

Step 2: Click Other troubleshooters. 

Step 3: Scroll to find the Update Troubleshooter and click the Run button. 

This should automatically fix the problem. 


Run an SFC Scan

Corrupt files are the number one reason your PC might behave weirdly. Here’s how you can get rid of them and potentially resolve your issue. 

Step 1: Press Windows Key + S to bring up the Cortana/Search box and search for Powershell. Open Windows Powershell from the search results.

Manually install the update

Another solution you can try is to manually install the update from the Microsoft Update Catalog. Just head over to the catalogue site, type in the update number, in this case, KB5016691, and manually download the update to install it much like you would a program. 


Repair your system

If nothing else works, the best way to get rid of the error is by simply reinstalling or repairing your OS. 

The Windows Media Creation tool is a great way to install Windows and repair the OS. Using this, you can perform a clean installation or repair your OS without affecting your data.
