Windows 11 version 25H2 is coming later this year, possible build number discovered

I have had problems in the past if I have forgotten to put apps like O&O ShutUP to default & other such great additions to my life before any major upgrade.
It could be the problem. A friend had a similar issue two years ago. Windows downloaded and installed the update. The update hit 100% after a restart, then said it was "cleaning and reverting the system." Windows reported an unsuccessful update upon reaching the desktop. He eventually updated Windows after uninstalling his security software.
I disable MD realtime protection with every Windows update to speed up the install.
I tried that and it still failed with the same error. May have to try uninstalling ESET. Thanks for the suggestion.
Microsoft confirms Windows 11 25H2, might make Windows more stable
Microsoft has confirmed that the next release of Windows is called Windows 11 25H2, and it’s going to be a minor update deployed via an enablement package. Windows Latest correctly predicted this in March 2025, and newer findings confirmed it again in April 2025. And now, it’s official. In a...

A more stable release
Unlike last year’s update, Windows 11 25H2 will focus more on fixing issues, including those with the File Explorer. One of the recent builds recently patched a long-standing bug where File Explorer’s “Home” tab takes several seconds to load. And we’re also seeing improvements in Settings’ “Home” page load speed in preview builds.
You’ll eventually get all of these fixes in 24H2 as well, but 25H2 will ship with quality improvements out of the box.
Windows 11 25H2 officially gives Microsoft time to focus on bug fixes rather than adding new features because it doesn’t have to promote the release as a “feature upgrade.”
Based on the information we have, Windows 11 2025 Update will begin rolling out to everyone in October or around that period. It will reset the support lifecycle clock. Enterprises will get 36 months of support, and Pro/Home (consumer editions) will be supported for 24 months.
Uninstalled AdGuard for Windows and tried but the update failed again. Then I uninstalled ESET IS and AppCheck and attempted the update, still failed with the same error. Seems like it's not meant to be on my system.
No, but each time the 24H2 update fails it reverts back to 23H2.
I hope you restarted the system after uninstalling the programs. Are you using any system optimizer tools like O&O ShutUp, etc.? How are you updating Windows? Maybe download the ISO and try an in-place upgrade. You can also run the commands "chkdsk /f" and "sfc /scannow" using an elevated Command Prompt to check for any issues on the system.
I always reboot after uninstalling any programs, and I've tried the repair installation but it fails with the same error. I've run chkdsk and sfc commands with no change. Thanks!
Without a backup, it appears your only hope is a clean install, my friend.
I know my system met all hardware requirements for Windows 11 up thru 23H2, didn't bypass any requirements when installing and updating the OS.
What reasoning is this conclusion based on?
@Bill K are you ready to take the plunge? Have you backed up all files, etc. in preparation?
BTW - creating a security configuration might be of use in getting future troubleshooting help from members.
Think I'm going to leave well enough alone and stay locked to 23H2 by using InControl software, which allows me to still receive available updates. I was fine trying to perform the 24H2 update and have spent many hours trying to do so, but don't want to do a clean OS re-install and lose all of my software and the numerous related settings in the process.
Not a long term solution. 23H2 end-of-life is 11/11/25, including security updates.

According to Microsoft's description, a Windows repair installation involves replacing the currently installed version of Windows with a completely new installation of the operating system. I therefore assume that there are no significant differences compared to a clean installation of the operating system, which also overwrites all other programs and data. Of course, I can't completely rule out the possibility that this might resolve a hidden error that has been preventing the installation of Windows 24H2.
I can understand that Bill K is reluctant to go through the hassle of completely reinstalling the operating system and all the applications he installed. It takes me at least a whole day to get everything back to the way it was before. I only do it when all other solutions have failed.
oldscholl is right, staying with Windows 23H2 is not a long-term solution.

Did you attempt an in-place upgrade using the Windows ISO, too? If not, consider trying it to see if it makes a difference.
Are there any Windows Update errors showing in Event Viewer?
