Windows 11 Beta Build 26120.3950: Enhancements in HDR, Energy Management, and Stability

The latest Windows 11 Beta Channel release, build 26120.3950 under KB5055653, is shaping up as a multifaceted update blending high-visibility features with a series of targeted improvements expected to resonate with both enterprise users and general enthusiasts alike. Most notably, Microsoft’s ongoing efforts toward better HDR control, energy optimization through integration with Microsoft Intune, and various quality-of-life enhancements in the Windows Update system illustrate the company’s continued emphasis on both visual excellence and manageability. The build also exemplifies Microsoft’s agile approach to rolling releases, as new features are being enabled gradually via toggles—underscoring a clear intent to study feedback and minimize systemic risk.

A Closer Look at Key New Features​

Energy Saver Integration with Microsoft Intune​

One of the central highlights in KB5055653 is the debut of energy saver policy management within Microsoft Intune. IT administrators can now enforce and tailor energy saver settings on Windows 11 devices using Group Policy or Mobile Device Management (MDM). The policy, located under Computer Configuration > Administrative Templates > System > Power Management > Energy Saver Settings, introduces the option “Enable Energy Saver to Always Be On.” This lets organizations push settings that intelligently reduce screen brightness, curb background activity, and lengthen battery longevity—without forfeiting device performance.
This move is especially timely as sustainability emerges as a core concern in enterprise IT. According to Microsoft’s documentation, the energy saver setting manages multiple system aspects to reduce power draw, and integrating it into Intune brings these controls under a central, cloud-based umbrella. This reduces IT overhead and ensures compliance with green computing initiatives. Independent reporting by ZDNet and Microsoft’s own Windows Insider Blog confirm both the scope and method of deployment, providing strong credibility for the announced capabilities.

HDR Experience—Clarity and Customization​

Microsoft has pushed forward in refining display settings, specifically for devices equipped with modern high dynamic range (HDR) panels. The HDR management improvements in KB5055653 offer several practical enhancements:

• Clearer Wording: The “Use HDR” toggle now clarifies which types of media are supported, eliminating confusion for users when choosing display options.
• New Streaming Options: Even when HDR is “off,” users on compatible panels may now permit HDR video streaming, addressing a long-standing gap where display capabilities and streaming preferences sometimes clashed.
• Dolby Vision Independence: For users with Dolby Vision displays, Microsoft now allows toggling Dolby Vision support separately from the main HDR setting. This creates a direct benefit for video professionals and content consumers who demand granular control over their visual experience.

The rollout is confirmed directly within Microsoft’s official Windows Insider documentation. Furthermore, reviews on outlets such as The Verge corroborate the growing focus on visual fidelity in Windows 11 and praise the effort to harmonize advanced display capabilities with user-friendly controls.

Windows Update Enhancements​

Quality and reliability are perennial concerns with the Windows Update mechanism, and KB5055653 attempts to address several pain points. Among the most notable improvements:

• Cumulative Update Stability: The build resolves an issue where updates could fail with error code 0x800f081f after a system reset—an issue previously documented on the Microsoft Answers forums and independent tech blogs like Neowin. By closing this gap, Microsoft lowers the risk tied to post-recovery state updates, a scenario increasingly likely in enterprise images and field deployments.
• Build Version Reporting: Some users experienced DR discrepancies after resetting a PC, where the build number would erroneously display as 26100 instead of the actual 26120. Although this bug reportedly does not block further updates and is slated for resolution in future releases, it underscores the complexity of maintaining version integrity in a rolling update ecosystem.

Taskbar and System Tray Polishing​

Microsoft’s steady refinement of the Windows taskbar is also evident in this release, with cosmetic and usability tweaks meant to streamline notification management and enhance clarity:

• The “needy state pill”—a visual indicator for apps requiring user attention—has been widened and rendered more visible, reducing ambiguity for multitasking users.
• Administrative control over pinned apps receives a boost: with the new PinGeneration option, IT admins can allow users to unpin specific apps without those items being automatically re-added upon the next policy refresh.

Such changes, while minor in isolation, add up to a more consistent and pleasant day-to-day experience, as echoed in user forums and ongoing feedback channels.

Recall (Preview) and Click to Do: Experimental, yet Controversial​

The Recall feature—currently in preview—reflects Microsoft’s continuing expansion into AI-powered productivity. The company is reportedly “trying out different treatments of the Recall UI,” including adjustments to the location of timeline and snapshot actions. Importantly, Microsoft emphasizes user control: Recall can be fully removed through the “Turn Windows features on or off” interface. Moreover, binaries relating to Recall are routinely purged over time and are non-executable when in maintenance states, a point Microsoft reiterates in official notes. This attention to transparency comes amid prior privacy concerns reported by outlets such as Ars Technica, which advocated for clearer user options and more inclusive data removal mechanisms.
Meanwhile, Click to Do’s intelligent text actions, now fully running locally instead of via cloud endpoints, mark a notable shift toward privacy and speed. These changes align with broader industry trends, as local moderation and AI processing reduce both latency and exposure to external privacy risks—offering users and organizations greater confidence in adopting new workflows.

Notable Fixes and Performance Improvements​

Beyond new features, KB5055653 addresses several platform-level bugs:

• Taskbar Keyboard Focus: An underlying issue causing unwanted focus on widgets during login (sometimes spawning unintended widget invocation) is resolved.
• App Switching: The WIN + CTRL key combo, previously non-functional for cycling through open app windows, is restored.
• Audio Startup Sound: A bug that could prevent the startup sound from playing—despite being enabled—is fixed.
• Display Scaling After Sleep: Microsoft addresses reports of unexpected scaling and window position changes following sleep/resume cycles, a recurring pain point for users with multi-monitor setups.

Each of these corrections has been validated in Microsoft’s official changelog, with user-reported confirmations in online communities such as Reddit and the Microsoft Tech Community.

Known Issues and Ongoing Investigations​

Despite the array of fixes, KB5055653 still exhibits a handful of known limitations that prospective adopters should weigh carefully.

• Beta Channel Enrollment: Users joining the Beta Channel will no longer receive prior build 26120.3360, but only the most current release—raising questions about historical regression test coverage.
• Post-Reset Build Reporting: As noted, build version misreporting persists after a “PC reset” via Settings > System > Recovery, though it does not block subsequent updates.
• Safe Mode Instability: Reports indicate that after recent flights, key Windows UI elements (including File Explorer and Start menu) may not load successfully in Safe Mode.
• Xbox Controller Bluetooth Issues: Some Insiders report that Bluetooth-linked Xbox Controllers can cause a system bugcheck. Microsoft advises users to uninstall a certain driver through Device Manager (“Devices by Driver” view), though the instructions reference a placeholder driver name (“ ( )”). Until more precise guidance is issued, affected users should proceed with caution.
• Live Captions Crashing: The newly documented issue with live captions can cause the feature to crash on this build, especially concerning for those relying on accessibility tools.
• Account Manager Access: There are growing reports that clicking the profile picture fails to summon the Account Manager within the Start menu, likely a regression from prior builds.
• Task Manager CPU Display: After the recent addition of a CPU Utility column, System Idle Process reportedly always shows “0”—introducing confusion for anyone monitoring resource allocation.

These unresolved bugs are subject to investigation, and users are encouraged to consult Microsoft’s Insider Program hub for up-to-date mitigation strategies.

Critical Analysis: Strengths and Potential Pitfalls​
