Microsoft has officially launched Windows 11 build 27774 in the Canary Channel of the Windows Insider Program, showcasing an array of captivating improvements and features, alongside vital bug fixes.
According to Microsoft, this new build introduces the innovative “Administrator Protection” feature integrated within the Windows Security app. A critical update for users, this feature alerts you during a clean installation that formatting or deleting partitions will irreversibly erase all data on the selected drive.
The latest iteration also rectifies several issues concerning Personalization settings and stabilizes the Xbox app, addressing crashes reported by many users.
Unveiling the Administrator Protection Feature
The “Administrator Protection” feature provides an enhanced layer of security via the Windows Security app. Once activated, it requires explicit authorization whenever an untrusted or unsigned application attempts to make significant changes to your system.
The color scheme used in the interface plays a crucial role; applications deemed potentially harmful will be highlighted in yellow, while trusted and signed applications will use a lighter palette. This visual distinction helps users quickly assess the safety of the apps they’re considering.

To activate this crucial security feature, follow these steps:
- Open Windows Security.
- Navigate to Account Protection.
- Click on Administrator Protection Settings.
- Flip the toggle for Administrator Protection to enable it.
- Restart your computer to apply changes.

This feature distinguishes itself from the more generalized “User Account Control” (UAC). While UAC serves as an overarching security barrier within the operating system, Administrator Protection is specifically designed to prevent unauthorized manipulations of elevated sessions, safeguarding your data comprehensively.
Updated Warnings during Windows Setup
This Windows 11 build also improves the installation experience by incorporating crucial warnings. When utilizing the drive manager for installation, users will receive clear alerts indicating that data will be lost if partitions are formatted or deleted.

The format partition warning states: “You will lose all data on this partition if you format it. Proceed with this operation only if you are okay with removing all data on this partition.”

The delete partition warning reads: “You will lose all data on this partition if you delete it. Proceed with this operation only if you are okay with removing all data on this partition.” These notifications are crucial for minimizing accidental data loss during the installation process.
Addressing System Fixes
In addition to the new features, this build addresses significant bugs, including issues with window borders that failed to display the chosen accent color. Animation glitches and unexpected crashes in the Xbox app have also been resolved, enhancing overall user satisfaction.
Installing the Preview
To get started with these latest Windows 11 builds, you will need to enroll your device in the Canary Channel via the “Windows Insider Program.” Navigate to the “Update & Security” section in your settings, select the program, and opt for the “Get the latest updates as soon as they’re available” feature. Click on the “Check for Updates” button to proceed with downloading the latest build.
Additionally, Microsoft offers an ISO file for Windows 11 build 27774, giving users more flexibility in installation options.
