Windows 11 Cumulative Update not downloading and installing.

uninstall .NET 4.8, that let mine update

That’s interesting. Let’s see if it works for others.

I also have the same problem. Since 06/2022 cumulative update, all cumulative updates have failed to install. 07/2022 is also failing to install. I've run DISM and SFC and they don't report any errors.

You can chase this "thing" all day and find nothing wrong. The In-place re-install took about 1.5 hours and that fixed it. Sometimes it just isn't worth trying this and that trying to fix a problem.

Good luck to you.

That would (and might actually) be useful if the problem does not recur on a regular basis.

I agree. I had a problem installing KB5013889. Tried all the usual commands (fsc /scannow, etc.) nothing worked.

Finally called MS Support. They showed me where to download the Windows 11 ISO file. I ran it and everything is good now. It's a simple repair that did not affect my files, settings or apps. My computer is just the same as it was prior to running the repair. Haven't been able to say thank you MS Support for a while but in this case they were right on the money. Thank you MS Support!

This is the link: Download Windows 11 (microsoft.com)

Once on the website, click on the second choice "Create Windows Installation Media". Select "Download Now" and follow instructions to create the ISO file (Not USB File). I saved the file to the desktop. Once downloaded, double-click the file, let it run and you'll back to normal again in no time.
