Windows 11 24H2/25H2/26H2: Problems with preview update KB5124010

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.

Is VLC taking an agonizingly long time to start up on Windows 11? Microsoft Defender is to blame

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.

Devs blame Windows for VLC media player bug that causes 33-second delay when playing MP3 files

VLC, the open-source media player, is experiencing delays of up to 33 seconds when playing MP3 files on Windows 11, attributed to a recent update to Microsoft Defender that conflicts with VLC’s plugin cache. Developer Jonathan Blow criticized VLC for this issue, prompting the VLC team to clarify that the problem stems from Microsoft Defender quarantining the plugins.cache file. Users can resolve the issue by reinstalling VLC or regenerating the plugin cache, although this will reset personalized settings. Adding an exception for VLC in Microsoft Defender may prevent future issues. Microsoft has not yet commented on the situation.

A Windows Defender bug is making VLC take 30 seconds to open an MP3 file

Jonathan Blow criticized the VLC media player for significant performance issues, specifically a 33-second delay in loading MP3 files, and announced his intention to switch to Microsoft Media Player. The VideoLAN team responded, attributing the delays to a known issue with Microsoft’s Windows Defender antivirus software, which quarantines the VLC plugin cache. They suggested users could resolve the issue by reinstalling VLC or regenerating the plugin cache. VLC has been downloaded over 6 billion times across various platforms. Microsoft Defender has been known to cause false positives and interfere with third-party applications. Some users have found success using alternative antivirus solutions like Bitdefender Antivirus Free to avoid conflicts with VLC. Additionally, there are suggestions that using VLC for MP3 playback may not be practical, and switching to Microsoft Media Player is viewed unfavorably compared to alternatives like Foobar2000.
