Windows 11 Insider Preview Build 27774: What’s New?

On January 16, 2025, Microsoft announced the release of Windows 11 Insider Preview Build 27774 to the Canary Channel. This update brings a mix of improvements and fixes aimed at enhancing the user experience.

Key Improvements and Features

One of the most notable changes is the introduction of a confirmation dialog during installation. Users will now see this prompt when formatting or deleting partitions from installation media.

Additionally, Administrator protection can now be enabled directly from Windows Security settings. This feature empowers home users to manage their security settings without needing IT assistance. However, enabling this option requires a system reboot.

“Administrator protection can now be enabled from Windows Security settings under the Account Protection tab.”

Fixes and Resolved Issues

This build addresses several underlying issues. For instance, it fixes the accent-colored window borders that were not displaying correctly. Moreover, it resolves problems with window animations, ensuring a smoother experience.

Another significant fix involves the Xbox app, which previously failed to launch. Users can now expect a more reliable performance from this application.

Known Issues to Watch

Despite the improvements, there are known issues to be aware of. Users transitioning from other channels to the Canary Channel may encounter problems with Windows Hello PIN and biometrics. The error message “Something went wrong, and your PIN isn’t available” may appear.

“If you are joining the Canary Channel on a new Copilot+ PC, you will lose Windows Hello PIN and biometrics.”

Additionally, users may experience rendering issues when minimizing and restoring File Explorer windows. Remote Desktop users should note that launching MTSC.exe may fail with error 0x80080005. A workaround is to run it as an administrator.

Final Thoughts

The Canary Channel builds are experimental and may not represent final features. Microsoft encourages feedback to refine these updates further. Remember, switching channels requires a clean installation of Windows 11.

For those eager to explore the latest developments, this build offers a glimpse into the future of Windows 11. Stay tuned for more updates as Microsoft continues to innovate.
