Microsoft has rolled out Windows 11 KB5050094 as part of its January 2023 Preview Update, delivering critical fixes and performance improvements that address some of the OS's most persistent issues. This optional update (build 22621.1192) focuses on enhancing gaming experiences, audio quality, and File Explorer stability while introducing subtle refinements to the Taskbar.

What’s New in KB5050094?

The update brings several noteworthy improvements:

  • Auto HDR Enhancements: Microsoft has fine-tuned Auto HDR for supported games, reducing visual artifacts and improving color accuracy in dynamic scenes.
  • DAC Audio Fixes: Resolved an issue where high-end USB DACs (Digital-to-Analog Converters) would occasionally produce distorted audio or fail to initialize properly.
  • File Explorer Reliability: Addressed multiple crashes related to context menu interactions and folder navigation.
  • Taskbar Tweaks: Improved responsiveness when opening the Start menu or switching between virtual desktops.

Gaming Improvements in Detail

Auto HDR Gets Smarter

Windows 11's Auto HDR feature, which automatically upgrades DirectX 11/12 games to HDR, has received significant tuning. Users report:

  • Smoother transitions between SDR and HDR content
  • Reduced banding in gradient-heavy games
  • Better preservation of artistic intent in stylized games

DirectStorage Optimization

While not explicitly mentioned in the changelog, early testing shows improved asset loading times in DirectStorage-enabled games like Forspoken.

Audio Fixes That Matter

The DAC audio improvements specifically target:

  • USB Audio Class 2.0 Devices: Fixes random disconnects during high-bitrate playback
  • DSD (Direct Stream Digital) Support: Resolves pops/clicks when switching between PCM and DSD modes
  • WASAPI Exclusive Mode: Addresses timing issues that caused jitter in professional audio applications

File Explorer and Shell Fixes

KB5050094 tackles several pain points:

  • Context Menu Lag: The infamous right-click delay when working with cloud-stored files has been reduced
  • Folder Preview Stability: Fixed crashes when generating thumbnails for certain RAW image formats
  • Drag-and-Drop Reliability: Improved when moving files between tabs in the new File Explorer

Taskbar and Start Menu Refinements

Subtle but welcome changes include:

  • 15% faster Start menu opening times on average
  • Better icon alignment when using small taskbar mode
  • Fixed a bug that caused search highlights to disappear prematurely

  1. Widgets Panel: May show incorrect weather information for some locations
