Windows 11 Insider Preview Build 27871: What’s New in the Canary Channel
Microsoft just dropped Windows 11 Insider Preview Build 27871 in the Canary Channel. This update is packed with fresh features and fixes aimed at enhancing your Windows experience. Let’s dive into the highlights and what tech enthusiasts should know.
Energy Saver Management Now in Microsoft Intune
One of the biggest updates is the integration of Energy Saver settings into Microsoft Intune. IT admins can now control energy saver options across Windows 11 devices using group policies or Mobile Device Management (MDM). This feature smartly balances battery life by limiting background activity and dimming screens when needed.
As Microsoft explains,
“The energy saver group policy helps reduce overall energy consumption, saving costs and supporting environmental sustainability.”This is a win-win for businesses and eco-conscious users alike.
Phone Link Gets a Major Boost
The Phone Link app is back with upgrades for both Android and iPhone users. Notifications from your phone now appear grouped by app directly in the Start menu. Plus, Android users can mirror their device screens with just one click.
iPhone users aren’t left out either — you can now access your iCloud photos and memories right from the Start menu. This seamless integration makes juggling devices easier than ever.
Taskbar and System Tray Improvements
Microsoft has tweaked the taskbar to make attention-needed apps more visible. The “needy state pill” indicator is now wider, making it easier to spot apps like Teams that require your focus.
Important Bug Fixes You Should Know
This build addresses a slew of issues, including:
- Fixing virtualization problems affecting VMware Workstation.
- Resolving File Explorer crashes when using touch or searching with disconnected network drives.
- Improving keyboard navigation and widget focus on the taskbar.
- Correcting audio playback issues with high-sample-rate devices.
- Fixing voice typing glitches in the Chinese touch keyboard layout.
These fixes collectively polish the Windows 11 experience, especially for power users relying on virtualization and multitasking.
Known Issues and Insider Reminders
Some bugs remain, such as taskbar acrylic material not showing properly and PIN login errors on Copilot+ PCs. Microsoft advises Insiders to recreate their PIN if affected. Also, switching channels may require a clean Windows install.
Remember, Canary Channel builds are experimental. Features may change or disappear as Microsoft tests new concepts. As they put it,
“Features may never get released beyond Windows Insiders.”So, expect surprises and keep feedback coming!
Final Thoughts
Build 27871 is a solid update that blends energy efficiency, device integration, and bug fixes. If you’re a Windows Insider in the Canary Channel, it’s worth exploring these new tools and improvements. Stay tuned for more updates as Microsoft refines Windows 11 for everyone.
