Windows 11 KB5055653 Update: Improvements in HDR, Power Management, and Stability

Microsoft’s ongoing commitment to iterative improvement in Windows 11 is once again demonstrated with the release of KB5055653 for Beta Channel users, also known as build 26120.3950. Far from a major headline-grabbing update, this release exemplifies Microsoft’s nuanced approach to enhancing day-to-day user experience, with a particular focus on HDR display management, power efficiency for enterprise environments, subtle visual refinements, and greater stability in Windows Update operations. Each of these facets is increasingly relevant as Windows 11 matures across both home and professional deployment scenarios.

Enhanced HDR Controls: Meeting a Growing Demand​

High dynamic range (HDR) support is no longer a niche feature for media aficionados and gamers—it is becoming mainstream as display technology evolves and the price of capable monitors drops. One of the key improvements in build 26120.3950 involves the update of HDR controls, mirroring advances first seen in the Dev Channel’s KB5055651.
With the current Beta release, Windows 11 now exposes more detailed and granular settings for users with HDR-capable displays. This enables users to better tailor the way HDR content is presented, including, in some builds, the ability to fine-tune luminance, color accuracy, and SDR content mapping when HDR is engaged. While not every setting is available to all users or display models, the new interface provides clearer access to advanced configuration, addressing longstanding user requests for increased control.
Critically, this enhancement is not merely cosmetic; it reflects industry feedback and Microsoft’s efforts to support both cutting-edge hardware and the growing catalog of HDR content in media applications and PC gaming. It also provides tangible benefit to creators, who can adjust their workflow and preview content with greater fidelity. According to recent hands-on coverage by Windows Report, users report smoother transitions between SDR and HDR content and improved handling of ambient brightness adjustments in compatible displays.

This feature fits neatly into Microsoft’s strategy for energy efficiency and sustainability, a theme previously explored in the Dev Channel. Fleet managers, especially in large organizations, now have increased leverage to enforce power-saving configurations, not just at initial setup but continually as business needs evolve. This can help drive down electricity consumption across hundreds or thousands of endpoints, aligning IT infrastructure with ESG (environmental, social, and governance) goals.
From a technical standpoint, Intune integration enables both pre-set and adaptive power profiles. Administrators can enforce or suggest settings remotely, reduce screen-on time, tweak sleep behaviors, and monitor compliance. These changes, while iterative, signal a continued refinement of Windows’ position as a cloud-managed endpoint OS, supporting both hybrid and traditional office deployments.

What IT Pros Should Know​

This update’s integration with Intune is particularly beneficial for organizations moving to zero-touch deployment and cloud-native device management models. By using modern policy frameworks, businesses can lower their administrative burden while simultaneously enhancing sustainability initiatives.
On the cautionary side, there are still transition friction points for organizations migrating from on-prem Group Policy Objects (GPOs) to cloud-based policies in Intune. Documentation suggests that not every setting is directly mapped, and some older devices require firmware or BIOS updates to fully support granular power controls. IT departments planning to utilize the new settings should closely review hardware compatibility lists and Microsoft’s deployment guidance before widespread rollout.

Taskbar Notifications: The “Needy” Indicator Gets a Facelift​

While interface tweaks often garner divisive reactions, even minor changes can enhance usability and cohesiveness. The revamped “needy” indicator—now a pill-shaped underline rather than a simple dot—signals apps that require user attention in a more visually coherent manner. This small modification, already tested in Dev Channel builds, represents Microsoft’s steady march toward unified design language and subtle user experience improvements.
Feedback from early adopters has highlighted the new indicator’s modern look and clearer distinction from other taskbar states, such as app notifications or background sync. The reformulation aligns well with Fluent Design System principles and the overall evolution of Windows 11’s visual identity.
Yet, it’s not without possible contention. Some users accustomed to the old dot notification may initially find the change disconcerting. It underscores a broader trend in OS UI updates—balancing the desire for freshness against the need for familiarity. Microsoft has, as of this release, not provided native options for reverting to the previous style short of registry edits or customization utilities.
