Windows 11 Beta Build 22635.5090: Key Fixes and Enhancements for Insiders

Microsoft has recently rolled out Windows 11 Beta build 22635.5090 to Windows Insiders on the Beta Channel, delivering a suite of important fixes and enhancements aimed at refining the user experience and improving daily productivity tasks. This update, part of Microsoft’s continuous effort to polish and optimize Windows 11 before official releases, offers vital bug fixes, UI improvements, and accessibility upgrades that benefit both casual and power users. Below, we delve into the context, technical specifics, and implications of this update.

Background: The Windows Insider Program and Beta Builds

The Windows Insider Program allows enthusiasts, developers, and IT professionals to test pre-release versions of Windows 11. It provides real-world feedback on new features, performance optimizations, and bug fixes before they reach the general public. Beta Channel builds, such as 22635.5090, are more stable than Dev Channel releases but still include experimental features and improvements in development. These preview builds serve as a critical feedback loop for Microsoft to fine-tune Windows 11.

Key Enhancements and Bug Fixes in Build 22635.5090

1. File Explorer Improvements

• Improved ZIP Extraction Performance:

One of the standout enhancements is optimized ZIP file extraction, which now performs faster and more efficiently, especially when dealing with archives containing numerous small files. This improvement targets smoother handling of file system operations by refining internal buffering and metadata processing, reducing CPU strain and wait times during compression and decompression tasks.

• Bug Fixes:
• Resolved an issue where launching File Explorer from the command line resulted in an empty address bar, enhancing navigation clarity.
• Fixed glitches in the Recommended section selection, now supporting multiple file selection via Shift-click without errors.
• Addressed visual misalignment of the "see more..." command button under specific screen resolution conditions, polishing UI consistency.

2. Input and System Stability

• Explorer.exe Crash Resolution:

Fixed a crash triggered by opening the input flyout, contributing to greater system uptime and stability.

• Login Experience on Lock Screen:

The update remedies a longstanding problem where the touch keyboard would occasionally launch twice during login attempts with touch input, causing system crashes and usability issues. This fix ensures only one instance of the touch keyboard appears, leading to smoother and more reliable authentication.

3. Accessibility and Voice Access Enhancements

• Expanded voice access command support now includes multiple English dialects such as UK, Indian, Australian, Canadian, and New Zealand English.
• Introduced advanced voice commands for text selection and editing, enabling commands like "Select from [word1] to [word2]" and formatting commands like "Bold that." These improvements significantly enhance accessibility, catering to users with varying speech preferences and regional accents.

4. UI and Productivity Tweaks

• Desktop Spotlight Improvements:

The Desktop Spotlight icon has been repositioned to the bottom right of the desktop and benefits from updated icon color schemes and backplates. These subtle visual updates aim to improve discoverability and ease of use of featured daily content.

• Taskbar and Start Menu Refinements:

Enhanced jump list functionality and improved notification handling bring a more intuitive and streamlined user experience, although some specific Start Menu app list crashes are still being addressed.

5. Miscellaneous Fixes

• Introduced an option to display seconds in the system tray clock, providing users with more detailed timekeeping options.
• Added VPN status icon in the system tray for better visibility of VPN connections.
• Various other minor tweaks to improve overall system responsiveness, taskbar behaviors, and touch keyboard settings.

Technical Insights

The improvements to ZIP extraction efficiency likely stem from better management of I/O operations and CPU resource allocation, perhaps through enhanced buffering and metadata handling. Such optimizations result in smoother file archiving workflows, which is essential for developers, IT professionals, and everyday users who frequently work with compressed files.

Fixes related to input stability and the lock screen’s touch keyboard appear to involve resolving race conditions in input subsystem management — ensuring smoother state transitions during critical user interactions like logging in.

Voice access command expansion reflects Microsoft’s ongoing investment in accessibility technologies, supporting a broader user base with diverse speech patterns, which can be crucial for inclusivity and productivity.

Implications and Impact

For Windows 11 Insiders, build 22635.5090 brings a tangible improvement in system stability and daily usability — particularly in file management and accessibility. The enhanced ZIP performance addresses a common pain point for users handling compressed archives, improving productivity across usage scenarios. The lock screen input fix is vital for touch-enabled devices, removing a persistent annoyance and enhancing reliability.

The widening of voice access capabilities underscores Microsoft’s commitment to building an inclusive operating system that accommodates users with different accessibility needs and regional diversity.

Although some known issues remain — such as occasional File Explorer sluggishness during window closure and specific Settings app glitches — Microsoft’s regular cadence of beta updates suggests these will be addressed in subsequent releases.

Looking Ahead

This update is a testament to Microsoft’s iterative development approach with Windows 11, relying heavily on Windows Insider feedback to smooth out rough edges before public rollouts. The improvements in build 22635.5090 lay a foundation for a more reliable, accessible, and productive Windows environment.

For insiders and curious users eager to experience early features and fixes, installing this beta build is recommended. Those outside the Insider Program should anticipate the eventual roll-out of these refinements in future cumulative updates.
