Windows 11 build 22000.100

Windows 11 build 22000.100 is the fourth Insider Preview build of Windows 11, which was released to the Dev Channel on 22 July 2021 and then to the Beta Channel on 29 July 2021.

Shell

 * The hidden icons flyout have been updated to reflect the new visual design.
 * Focus assist settings can now be accessed from the Notification Center.
 * Apps now flash red in the taskbar when background activity requires attention from the user.
 * Microsoft Teams chat integration in the taskbar has started rolling out to Insiders in the Dev Channel.

Bugfixes

 * Fixed issue where the date and time button would cause Explorer to crash on certain locales with Focus Assist disabled.
 * Fixed issue where the File Explorer would crash in a loop for users using the Russian display language if the battery level is at 100%.
 * Fixed bug where the close button on the new taskbar previews when hovered over didn't adjust to the rounded corners.

General

 * The UI might end up being an Windows 10 and 11 hybrid instead. It can be fixed by uninstalling and reinstalling the KB5004300 update.

Network

 * The network adapter that the VMware hypervisor uses for will not work on any of the N edition variants because the network adapter driver according to Device Manager fails to start with Code 10 with either upgrading or clean installing.

Shell

 * The options to open System and Windows Terminal may be missing from the Win menu.
 * The taskbar will sometimes flicker when switching input methods.
 * UAC prompts may display the incorrect text for some users. This can be fixed by ensuring that the user is on version  or later of their Local Experience Pack.

Desktop Window Manager

 * The hidden icons flyout may display without rounded corners.
 * Both the widgets and Microsoft Teams panels may appear blank on some GPUs. Disabling and enabling the GPU from device manager temporarily fixes the issue.
 * Elements such as menus may display under all visible windows after a full screen window is shown. Restarting the DWM process fixes this issue.

File Explorer

 * On some locales, File Explorer may crash in a loop if the battery level is at 100%.

= Lock screen = On the lock screen, the "Ctrl+Alt+Del" prompt now displays a lock icon with the same text as we had in Windows 10.
