Windows 11 Cumulative Update not downloading and installing.

Version 22H2 (OS Build 22621.963)

in response to your question it is not a new computer and I had updated to win 11 from win 10 last year and yes I had to reinstall windows 11 as per Charlies post:

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.

Reply  After following these instructions everything is working fine again

you say it ok now after MS gave you instructions, but was it a brand new computer with the latest windows? you had to install a new / latest version yourself.

Can you share the instructions they gave you?

I think the best way to solve this problem is by downloading a Windows 11 .ISO and re-install the whole system.

My wife and I have similar desktop Dell computers, I have more memory and external video card. Both with SSD OS drive Boot drive size with plenty space. My computer will NOT install update while her computer installed the update, without any problem.

ISO disc installation FAILS "not sure having enough space on hard drive" What? 160 GB free
