KB5015818: Release Preview Update for Windows 11 v 22H2 Build 22621.232

It won't install.

Thank you, I've commented and upvoted.

I've tried to install this few times and the same results. The update downloads, then "Installing", then "Pending restart". I restart the system and the installation fails with an on screen message "Something didn't go as planned...". I've tried few time and same result.

Events during the reboot:

The progress goes to 30% then automatic reboot. Upon automatic resume, the progress continues from 30% to 36% with another automatic reboot. Upon resuming at 36% the progress holds there for about 15-20 seconds with another reboot. This time, upon resuming, the on screen message of "Something didn't go as planned..." is displayed. They system revert back after several additional reboots.

Hi guys,

I assume you guys have run sfc and dism commands.

Suggest you download the ISO of 22621.1 from here:

https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso

Mount the image within windows and run setup.exe to do a repair install. It should upgrade properly from this point. You will retain all your files. As with any major upgrade, ensure your important files are backed up.

I had same issue coming from build 22621.169 upgrading CU to 22621.290. This worked in that scenario, should work for .232 as well. Otherwise you might have to clean install and start fresh.

Regards,

There is a thread in hub already (in French, but it's there at least: https://aka.ms/AAhh39j).

Also created another one in english with the exact details of that specific issue: https://aka.ms/AAhgocq.
