On September 22, 2026, Microsoft released the optional Preview Update KB5124010 for Windows 11 versions 24H2, 25H2, and 26H2, aimed at enhancing performance and addressing various issues, with broader distribution planned for October 2026. User feedback indicated concerns about complications from the update. A user reported that applications were crashing due to issues with the library file msmpeg2ac3dec.dll when multiple MP3 files were played simultaneously, affecting older games like SimCity 4 and Fallout New Vegas. The user's company’s telephone system, using innovaphone, also experienced crashes with the myApps client. The msmpeg2ac3dec.dll file was found only on systems upgraded from Windows 11 22H2, while fresh installations of 24H2 or 25H2 did not include it. A workaround involving the installation of "LAV Filters" was tested and found to resolve the crashing issue. Microsoft acknowledged the issues related to the Preview Update KB5124010, stating that applications requiring AC-3 audio decoding might close unexpectedly and that they are working on a resolution for this problem in a future update.

Dave W. Plummer has developed a new Task Manager called TMOG (Task Manager OG) from a 107-page specification. He is the original architect of the 80KB Task Manager for Windows NT 4.0, released in 1996. TMOG is compatible with Windows 11, macOS, and Linux. Plummer began working on TMOG while waiting at the hospital during his son's emergency appendectomy and completed a functional app by the time his son was discharged. He further enhanced TMOG during a subsequent hospital stay due to his son's internal bleeding. The app features 60 Hz animations and various customization options. Initial versions were created in four and a half hours and functioned well on the first attempt. User feedback on beta versions has been positive, although some minor issues remain.

Users of VLC on Windows 11 have experienced delays of up to 33 seconds for MP3 playback due to a bug in Microsoft Defender that interferes with VLC's plugin cache. VideoLAN has clarified that this issue is not a reflection of VLC's reliability. Affected users can resolve the problem by adding the VLC folder as an exception in Windows Defender or by regenerating the plugin cache. Jonathan Blow, a game developer, highlighted the issue in a tweet, prompting discussions about the state of open-source software. Other users have reported similar delays, even on Windows 10. VideoLAN emphasized that the problem lies with Microsoft Defender, not with VLC itself.
