Microsoft has recently released new Windows 11 Builds to Canary channels. Microsoft has introduced a new “Energy saver” in the Canary channel Build 27871.Here is what’s new in Windows 11 Build 27871 that was released to the Canary channel.
What’s new with Build 27871
Energy saver now available in Microsoft Intune
We are bringing the ability to manage energy saver in Windows 11 to Microsoft Intune to allow IT administrators to control the energy saver settings on Windows 11 PCs through group policies and Mobile Device Management (MDM) configurations.
This feature, when enabled, intelligently balances your battery use, so it can last longer between charges. It extends battery life by managing power usage efficiently. It limits background activity and reduces screen brightness, ensuring that devices consume less power while maintaining optimal performance. By automatically managing system processes and power usage, the energy saver group policy helps reduce overall energy consumption. This not only saves costs but also contributes to environmental sustainability.
IT administrators can activate the policy by using either method below:
- Local Group Policy Editor in Windows 11
- Microsoft Intune Admin Center
The path for the new policy configuration can be found at in Local Group Policy Editor by navigating to Computer Configuration > Administrative Templates > System > Power Management > Energy Saver Settings and “Enable Energy Saver to Always Be On”.
Changes and Improvements
[Phone Link]
Phone companion for the Start menu is rolling out (again) for Windows Insiders in the Canary Channel along with the following improvements:
- Instantly see notifications from your mobile device apps — grouped by app for easy catch-up, right from your Start menu.
- Mirror your Android device’s screen with a single click from your Start menu. Simply click on your device’s icon or access the option from the footer menu to quickly launch device screen mirroring.
- Your iPhone© memories are now accessible from the Start menu. iCloud for Windows users can see recently synced photos and quickly access their iCloud photos all within the Start menu.
Note: Screen mirroring is only supported on certain Android devices. See Setting up and using phone screen in the Phone Link – Microsoft Support for more details on device support.
[Taskbar & System Tray]
- We have adjusted the needy state pill under apps on the taskbar that need attention to be wider and more visible.
Fixes
[General]
- We have mitigated the issue where if Virtualization Based Security is enabled, applications dependent on virtualization, such as VMware Workstation, would lose the ability to run unless the “Windows Hypervisor Platform” Windows optional component is installed on the system.
[File Explorer]
- Fixed an issue where if you had disconnected network drives when doing a search from Home it might prevent searches from executing and you’d remain on Home.
- Fixed an issue where tapping the View button in File Explorer with touch would crash File Explorer.
[Taskbar]
- Fixed an issue where WIN + CTRL + Number wasn’t working anymore for switching windows in the taskbar.
- Fixed an underlying issue which was causing keyboard focus to get set to widgets in the taskbar on login, which could make widgets unexpectedly invoke.
- Fixed an issue when using Tab and Shift + Tab to move keyboard focus around the taskbar, where if keyboard focus went backwards at least once you could get keyboard focus stuck on the taskbar frame, causing some screen readers to just say “pane”.
[Settings]
- Fixed an issue where hovering over the cards at the top of Settings > System > About wasn’t showing the correct corner radius.
- Fixed an issue where the storage card in Settings > System > About showed a garbage character instead of the proper disk size.
[Administrator Protection]
- Fixed an issue where when using Administrator Protection, some apps might not follow your preference if it was set to dark mode.
[Task Manager]
- Fixed the issue causing search and other options such as filtering in Task Manager to not work.
[Audio]
- Fixed an issue in the last few Canary flights where audio devices with high sampling (like 192Hz) and multiple channels weren’t producing sound.
- Fixed an issue which could cause the startup sound not to play, though it was enabled.
[Input]
- Fixed an issue where voice typing wouldn’t start from the touch keyboard when using the Chinese (Simplified) narrow layout.
- Fixed an issue where when using the Symbols section of the touch keyboard, pressing the key to change pages might unexpectedly insert a character into password fields.
[Graphics]
- Fixed an issue which could cause unexpected scaling and window position changes after sleep/resume for some devices.
[Voice access]
- Fixed an issue which could voice access to freeze with error “working on it” when dictating.
[Other]
Fixed an issue causing an Administrative Templates error message when opening Group Policy Editor.[UPDATE 6/5] This issue is not completely fixed yet.- Fixed an issue where some of the commands when using xml to setup were unexpectedly not being run.
- Fixed an issue when installing Windows from installation media, where if you changed your keyboard layout from the default, it may still use the default when entering the product key.
- Fixed an issue when installing Windows from installation media, where certain partitions may show an extremely large erroneous size.
Known issues
[General]
- [IMPORTANT NOTE FOR COPILOT+ PCs] If you are joining the Canary Channel on a new Copilot+ PC from the Dev Channel, Release Preview Channel or retail, you will lose Windows Hello pin and biometrics to sign into your PC with error 0xd0000225 and error message “Something went wrong, and your PIN isn’t available”. You should be able to re-create your PIN by clicking “Set up my PIN”.
- We’re working on the fix for an underlying issue where the taskbar is unexpectedly not showing acrylic material after upgrading to the latest Canary builds. This is impacting a few other scenarios, leading to unexpected black or white in some UI.
- There is an issue causing an Administrative Templates error message to display when opening Group Policy Editor.
