Windows 11 Insider Preview Build 27891: What’s New in the Canary Channel?
Microsoft just dropped Windows 11 Insider Preview Build 27891 for the Canary Channel. This update packs a bunch of fixes and improvements, plus a fresh Microsoft Store update. If you’re a Windows Insider who loves testing early features, this build is worth checking out.
Major Updates and Fixes You Should Know
One big change is the removal of Windows PowerShell 0. Microsoft is officially deprecating it, signaling a move towards more modern tools. “More information will be shared in the coming months,” so stay tuned if you rely on PowerShell.
The update also fixes several annoying bugs. For example, the “Reset this PC” option now works properly after upgrading, which was broken in recent Canary builds. Plus, the taskbar’s acrylic material display glitch is resolved, fixing those weird black or white UI patches.
Windows Update downloads getting stuck at 2%? That’s fixed too. Language rendering issues in Vietnamese and Arabic have been corrected, so characters now display properly in places like Task Manager.
File Explorer and Settings Improvements
File Explorer’s address bar dropdown no longer gets cut off, making navigation smoother. Also, opening microphone properties in Settings won’t crash your system anymore. Bluetooth-related crashes in Settings and Quick Settings have been addressed as well.
Windowing, Task Manager, and Audio Fixes
The window minimizing animation now runs correctly. Task Manager’s CPU graphs use updated calculations, and the new CPU Utility column shows accurate data. Audio glitches causing system sounds to stop have been fixed, so notifications and volume slider clicks sound just right again.
Microsoft Store Update: Faster Installs from Featured Sections
Microsoft Store on Canary and Dev Channels gets a slick upgrade. You can now install apps and games directly from the top featured sections on the Store’s homepage. This cuts down the number of clicks and speeds up getting your favorite apps.
“Install directly from top featured sections: helping you download your favorite products in fewer steps.”
Give it a try and share your feedback via the Feedback Hub (WIN + F) under Microsoft Store.
Known Issues to Watch Out For
Heads up: Copilot+ PC users switching to Canary might lose Windows Hello PIN and biometrics temporarily. You can reset your PIN by clicking “Set up my PIN.” Also, Settings might crash when adjusting Power & Battery options, and Remote Desktop on Arm64 PCs may show graphical glitches.
Why Join the Canary Channel?
The Canary Channel is where Microsoft tests the newest platform changes early. Features here might never make it to public releases, so expect experimentation. If you want the latest but don’t mind some rough edges, this channel is for you.
“Features may change, be removed, or replaced and never get released beyond Windows Insiders.”
Remember, switching out of Canary requires a clean Windows 11 install. Also, the desktop watermark is normal for these pre-release builds.
Wrapping Up
Build 27891 is a solid step forward for Windows Insiders craving early access to fixes and new features. From PowerShell 0’s removal to smoother UI and Microsoft Store improvements, this update polishes the Windows 11 experience. Just watch out for the known issues, especially if you’re on specialized hardware.
Stay tuned for more updates as Microsoft continues refining Windows 11 behind the scenes!
