Microsoft Releases New Windows 11 Insider Preview Build to Dev Channel
Microsoft announced the release of Windows 11 Insider Preview Build 26200.5581 (KB5055651) to the Dev Channel. This update is part of the company’s ongoing effort to test and refine new features and improvements for the upcoming Windows 11 version 24H2. The release includes energy saver integration with Microsoft Intune, a significant addition for IT administrators managing Windows 11 devices.
Energy Saver Comes to Microsoft Intune
A key feature in this build is the ability to manage energy saver settings in Windows 11 through Microsoft Intune. This integration enables IT administrators to control power management policies on Windows 11 PCs via group policies or Mobile Device Management (MDM) configurations. The energy saver feature intelligently optimizes battery life by limiting background activity and reducing screen brightness, thereby lowering power consumption and supporting environmental sustainability. Administrators can activate this policy using the Local Group Policy Editor or the Microsoft Intune Admin Center.
Taskbar and System Tray Enhancements
The update introduces visual adjustments to the taskbar, making the "needy state pill" (indicating apps requiring attention) wider and more noticeable. For example, Microsoft Teams notifications on the taskbar will now be more visible. Additionally, administrators can now allow users to unpin specific apps from the taskbar, preventing them from being repinned during policy refresh cycles. This feature is configurable using the new PinGeneration option.
HDR and Graphics Improvements
Users will find enhanced HDR management settings under Settings > System > Display > HDR. The update clarifies the wording for "Use HDR" to better indicate supported media types. For PCs with HDR displays, users can now stream HDR video even when HDR is disabled in settings. Those with Dolby Vision displays can also toggle Dolby Vision mode independently of HDR, offering more flexibility in display preferences.
Fixes and Known Issues
This build addresses several issues, including:
- Taskbar fixes: Resolved an underlying problem causing unexpected widget invocation on login and fixed the WIN + CTRL + functionality for cycling through open app windows.
- Audio and graphics fixes: Ensured startup sounds play as intended and prevented unexpected scaling and window position changes after sleep/resume for some devices.
- Windows Update fix: Addressed an issue causing cumulative update failures (error 0x800f081f) after PC resets.
However, known issues remain, such as:
- Safe mode limitations: Core Windows surfaces (e.g., File Explorer, Start menu) may not load in safe mode.
- Xbox Controller connectivity: Some Insiders experience system crashes when using Xbox Controllers via Bluetooth, with a provided workaround involving driver uninstallation.
- Live Captions crashes: An ongoing investigation into Live Captions instability on this build.
Reminders for Windows Insiders
Microsoft reminded Dev Channel participants that updates are based on Windows 11, version 24H2, delivered through an enablement package. The company uses Control Feature Rollout technology to gradually introduce features to Insiders, with the option to toggle on early access to the latest updates via Settings > Windows Update. As always, feedback is crucial, and users are encouraged to report issues through the Feedback Hub.
The release highlights Microsoft’s continued focus on refining Windows 11, emphasizing power management, display capabilities, and user experience. As the development process progresses, Insiders can expect further updates and adjustments based on feedback, shaping the future of Windows 11.
