KB5031455 is not installing on some systems running Windows 11 version 22H2. In some cases, Windows 11 KB5031455 is also causing issues with games and the performance of apps like File Explorer, a problem which could be linked to the Windows 11 Moment 4 update.

Microsoft started rolling out KB5031455 to the general public as an optional update for Windows 11 22H2 or newer. It’s the first update to ship with Windows 11 Moment 4 features enabled by default, including Windows Copilot in supported regions, preview support for items in the Start menu, ungrouping for the taskbar and more.
Furthermore, it fixes several issues with Windows 11, including potential performance issues causing memory leaks. But ironically, the October 2023 optional update is turning out to be a disaster for users attempting to install the update and even those who have already installed it.
According to reports in our comments section, this Windows 11 update won’t install for many users. Sometimes, the installation would “run and fail, then reboot and run and fail again”.
Another user describes the update installation process as “crazy” as it “takes a long time to recover after rebooting several times”.
“I am having trouble installing this update. I have tried numerous times, and I get to 97%, and then I receive a message stating that it didn’t go well, and it reverses the update. I don’t know if it’s because I don’t have enough memory to update it or if I need to restore my laptop to factory operating and restart as new set up. This is an Alienware laptop, and I really don’t want to screw this one up,” one of our readers told Windows Latest.
Another Windows Latest reader flagged gaming issues after installing the optional cumulative update, stating in our comments: “The October insider preview build broke a few of my games. Some games I got from Epic, like Fortnite and Horizon Zero Dawn, crashed and refused to start.”
There are similar reports on Microsoft’s Feedback Hub, with one affected user noting, “2023-10 Cumulative Update Preview for Windows 11 Version 22H2 for x64-based Systems (KB5031455) fails to install with error 0x800f0984.”
According to reports seen by Windows Latest, Windows 11’s latest update fails to install due to weird and very unhelpful error messages:
- 0x800f081f
- 0x8007007e
- 0x8000ffff
- 0x800f0984
- 0x80073701
In our tests, we observed that KB5031455 update downloads but then stops during the installation attempts.
We don’t know how widespread these issues are, but we see reports everywhere, and we’ve also observed similar issues on one of our test machines.
