Windows 10: Update KB5016629 Impossible to install

Hello! I've tried to install this update countless times this month and it's practically impossible. I've read so many different ways to do it and nothing seems to work. I tried disabling MalwareBytes completely and trying someone suggested it, didn't work. I tried downloading ISO and installing it didn't work.. I literally have no idea what to do anymore.. I would greatly appreciate any help given.. Thank you!

2022-08 Cumulative Update for Windows 11 for x64-based Systems (KB5016629) will not install. Install error - 0x800f0988.

A search for an answer to this problem provides several recommendations. None, so far, have worked for me.

The first method I tried said to clean the temp files on your computer and restart it, then reset the update components.

1. Press Windows + R. Type TEMP and press enter. Delete all the files inside this folder. Repeat this step by typing %TEMP% and Prefetch. Delete everything on both folders too.

2. then Update Troubleshooter can help resolve the problem.

Select Start > Settings > System > Troubleshoot > Other troubleshooters. Next, under Most frequent, select Windows Update > Run.

note: I was not able to delete all of my temporary files because some were in use.

This method did not work, I still got the 'Install error - 0x800f0988'.

The second method said to go to Microsoft Update Catalog

and enter the KB number (KB5016629) into the search field. A list of updates is displayed. Find the appropriate update on the list and pick the download button for that file. Once downloaded, double-click on the file to install it.

The Windows Update Standalone Installer seemed to be working but finished with the message "Some updates were not installed. The following updates were not installed: Security Update for Windows (KB5016629)"

Are there any other methods I can try to get this 'important security update' installed?

 

Windows 11 Cannot install update KB5016629

Hi John,

Did as you said and removed Malwarebytes and turned off Net 3.5 and I think it has worked. Funny thing is that KB5016629 does not show in the Update history, but it DOES show in Control Panel, Programs and Features as an installed Update. My WinVer is now 22000.856. IS that the correct build? If so thank you so much for suggesting something different which actually seemed to work - I never want to see "Something didn't go as planned. No need to worry - undoing changes. Please keep your computer on" again!
