Windows 11 build 22000.51

Windows 11 build 22000.51 is the first Insider build of Windows 11. Photographs and a screenshot of this build were posted by a Microsoft employee (Anduin Xue) on 27 June 2021, but were later removed. It was released to insiders in the Dev Channel on 28 June 2021.

Taskbar
This build continues the taskbar revamp by introducing a new system tray and flyouts. All flyouts that have been left untouched in the previous builds, as well as jumplists have been updated with rounded corners. The system tray also now uses the Segoe UI Variable font as a side effect of using WinUI.

The Action Center and other flyouts have been replaced by new flyouts. Notifications are now combined with the calendar flyout in the Notification Center, accessible by clicking the clock widget. When there are unread notification, the clock shows the count in a badge at its right side. Similarly, when Focus Assist is enabled, the clock shows a moon icon at its right.

Icons for network and sound, which have also been updated since the previous builds, now act as a single widget, which when clicked shows the new Quick Settings incorporating quick actions from the Action Center, as well as the sound volume slider and media playback controls.

File Explorer
File Explorer has received a significant overhaul with a new toolbar replacing the previous used ribbon, as well as new menus.

Lock screen
This build introduces a new lock and login screen.
