Microsoft came up with Windows 11 Insider Preview Build 22621.440 and 22622.440 to the Beta Channel.

New in Build 22622.440

Taskbar Overflow

We’re reintroducing taskbar overflow, with a newly designed experience for Windows 11. This taskbar experience has been thoughtfully crafted to offer a more productive switching and launching experience when space is constrained. Your taskbar will automatically transition into this new overflow state when it reaches its maximum capacity. In this state, the taskbar will offer an entry point to an overflow menu that allows you to view all your overflowed apps in one space.

The overflow menu will contain many of the current taskbar behaviors users are familiar with, such as supporting pinned apps, jump list, and extended UI. After invoking overflow, the menu will quietly dismiss once you click outside of it or navigate to an application.

This should make it easier for you to know when something important happens related to these widgets and keep you informed of breaking news.

The content is meant to be quick and glanceable, with the ability to see more inside the widgets board if you click on it. However, if you don’t interact with the content update, the taskbar will return to showing you the weather.

Changes and Improved in Build 22622.440


  • We are beginning to roll out the updated “Open with” dialog box again to align with Windows 11 design principles. The updated dialog box honors a light and dark theme. We have also simplified the experience by making it possible to update your default app with just one click. Since reverting this change back in March, we’ve made performance improvements based on Insider feedback.new open with


  • We have updated the U.S. English (EN-US) handwriting model to be faster and more accurate. Use the updated Handwriting Panel for ink-to-text and let us know what you think.
