A little over a weekafter Microsoft launched Windows 11in an early preview with the Windows Insider program, the new operating system is already seeing some big updates.

Microsoft just announceda new Dev Channel build of Windows 11, improving the Start Menu and adding fixes that “make the Windows 11 experience even better.

The big improvement in this build ofWindows 11is a new search box in the Start Menu, making it easier to find what you’re looking for, without the need to open the dedicated search app. Other changes include the return of the Power Mode settings in the Power and Battery page, as well as the ability to right-click on the volume icon in the taskbar to troubleshoot sound problems.

Some smaller changes coming in this build relate to system alert dialogue boxes. The alert for battery running low and display settings all now feature Windows 11’s new visual design. Microsoft even simplified refreshing the desktop, so that you no longer need to click “show more options.”

Separate out-of-band patches fixed it in Windows 10, but today’s release patches up the remote code execution exploit in Windows 11. Other fixes cover bugs in the settings app, notifications, lock screen, Widgets, and more.
