Windows 11 Insider Preview Build 27783: What’s New in the Latest Canary Channel Update?

Microsoft is at it again, rolling out another cutting-edge update for Windows Insiders. The latest Windows 11 Insider Preview Build 27783, now available in the Canary Channel, brings exciting new features, improvements, and crucial fixes that enhance the overall user experience.

If you’re an early adopter who loves testing fresh Windows 11 features before they hit the mainstream, this update is worth your attention. From File Explorer enhancements to new keyboard shortcuts for Magnifier users, here’s everything you need to know.

A Smarter, More Connected File Explorer

One of the standout additions in Build 27783 is the revamped File Explorer Home, which now provides faster and more intuitive access to your shared files. If you're signed into Windows with your Microsoft account, you can now view files that have been shared with you via email, Teams chat, and other Microsoft services.

For business and enterprise users signed in with a Microsoft Entra ID (formerly Azure AD) account, the update goes even further—allowing you to see files shared both with and by you.

But that’s not all! Microsoft is expanding the variety of file types shown in File Explorer’s Recent, Favorites, and Shared sections. This means if you’ve been working with files from Microsoft Designer, Loop, Power BI, Forms, and other apps, they’ll now appear right at your fingertips.

 How to Access It:

Open File Explorer HomeClick on the new ‘Shared’ tabInstantly view files shared with or by you

This tweak makes collaboration easier than ever, removing the need to dig through emails or chats to find shared documents.

 Magnifier Gets More Accessible with New Keyboard Shortcuts

If you rely on Windows Magnifier, there's a nifty new shortcut in this update. You can now quickly toggle between your current zoom level and 1X zoom using:

 CTRL + ALT + Minus (-)

On top of that, Microsoft has added two new buttons within Magnifier:  Reset zoom to fit to screen  Reset zoom to last or preferred magnification

These changes ensure a more seamless experience for users who depend on Magnifier for accessibility or productivity purposes.

 Bug Fixes & Improvements You’ll Appreciate

No Windows update would be complete without a set of fixes and refinements—and Build 27783 delivers. Here are some of the biggest improvements:

Taskbar & System Tray Fixes

 Fixed a glitch where taskbar preview windows wouldn’t display properly when hovering over open apps.

 Keyboard & Input Enhancements

 Resolved an issue for Pinyin IME users where switching between windows (using ALT + Tab) would unexpectedly switch their input from Chinese to English.

 Windowing Fixes

 Fixed a problem that caused app windows to freeze unexpectedly when using ALT + Tab between certain apps.

 Graphics Settings Stability

 Fixed an issue that caused Settings to crash when accessing System > Display > Graphics.

 Remote Desktop Fixes

 Resolved a Remote Desktop display rendering bug  Fixed an issue where MTSC.exe would fail to launch on the previous build

 Other Performance Tweaks Memory leak in explorer.exe fixed – improving long-term system performance.  Fixed an issue where the shutdown /r /fw command wasn’t working properly.

 Known Issues You Should Be Aware Of

While Build 27783 brings plenty of improvements, there are some known issues that Insiders should watch out for:

 File Explorer Rendering Issues: If you minimize a File Explorer window in this build, it may not render correctly when restored.

 Windows Hello PIN Problems on Copilot+ PCs: If you switch to the Canary Channel from another Insider channel, your PIN or biometrics might not work. You’ll need to manually re-create your PIN.

 Hyper-V & WSL Issues: Microsoft is investigating reports that Hyper-V and Windows Subsystem for Linux (WSL) may not work properly after the last update.

 Workaround Tip: If you're experiencing issues with this build, make sure to report your feedback via the Windows Feedback Hub (WIN + F).

 Final Thoughts: Should You Install Build 27783?

If you're an Insider who loves getting a sneak peek at Windows 11's future, Build 27783 is worth a try—especially for the improved File Explorer and Magnifier enhancements. However, if you rely on Hyper-V, WSL, or Windows Hello PIN sign-in, you might want to hold off until Microsoft releases fixes for these issues.

As always, remember that Canary Channel builds are experimental—meaning some features might never make it to final Windows 11 releases. But if you enjoy testing out new capabilities and shaping the future of Windows, this update is a must-try.
