KB5031455 is failing to install on certain systems running Windows 11 version 22H2. Additionally, some users are experiencing issues with games and the performance of apps like File Explorer, which could be associated with the Windows 11 Moment 4 update.

Microsoft released KB5031455 on October 26 as an optional update for Windows 11 22H2 or newer. This update includes Windows 11 Moment 4 features such as Windows Copilot, ungrouping for the taskbar, and more. However, many users are encountering installation problems, with reports of failures at various stages and error messages such as 0x800f081f, 0x8007007e, 0x8000ffff, 0x800f0984, and 0x80073701.

Furthermore, some users have experienced gaming issues, such as crashes or games refusing to start, after installing the update.

Despite aiming to fix several bugs, including potential performance issues causing memory leaks, the October 2023 optional update appears to be problematic for users. Installation failures are common, with the update often running and failing multiple times, leading to lengthy recovery periods.

Users have expressed their difficulties with installing this update, with some considering restoring their laptops to factory settings or fearing that their devices may not have enough memory to support the update. Gaming-related problems have also been raised, particularly with games obtained from platforms like Epic, including Fortnite and Horizon Zero Dawn.

It is important to note that these game crashes are unrelated to the Xbox Game Pass bug that affected the Windows 11 October 2023 Update.

Reports of installation issues with Windows 11’s latest update have been submitted through Microsoft’s Feedback Hub. Error messages such as 0x800f081f, 0x8007007e, 0x8000ffff, 0x800f0984, and 0x80073701 have been commonly encountered.

The installation problems with Windows updates require Microsoft’s attention. While it is possible to install the update manually through the Microsoft Update Catalog in some cases, this method may not be effective for everyone.

Although the extent of these issues is unknown, numerous reports indicate widespread problems, including our own observations on a test machine.
