What's New in Windows 11 Build 22557

In addition to general improvements and refinements to Windows 11, this update brings a number of useful features and changes, the most notable of which is the Live Caption feature - a feature previously available only on Android devices. There are also new Do Not Disturb and Focus modes, new touch gestures, a better Start menu, a redesigned Task Manager, a battery life management interface, and more. Here are the details.

Start Menu Folder

Based on user feedback, Microsoft has introduced the first version of folders in this release. Folders can be created by simply dragging one application on top of another. You can add more apps to the folder, rearrange apps in the folder, and remove apps from the folder. Watch for further improvements, such as the ability to name and rename folders in Microsoft's upcoming release.

Live Caption

Real-time captioning will help everyone, especially including the hearing impaired, to better understand audio by viewing spoken content with captions. The subtitles are automatically generated on the device from any content with audio, and can be displayed at the top or bottom of the screen, or in a floating window. Microphone audio is also included, which may be helpful in face-to-face conversations.

Currently, live captioning supports English (US) content and can be enabled via the WIN + Ctrl + L keyboard shortcut.

No Not Disturb

Notification banners can now be easily silenced with Do Not Disturb mode. When you're ready to see the notifications you may have missed, you can find them in the Notification Center.

You can also control your notifications at any time. Under Settings > System > Notifications, you can set rules to automatically turn on Do Not Disturb.

For example, you can set Do Not Disturb to turn on automatically outside of your work hours. In addition, you can set priority notifications to control that incoming calls, reminders, and specific applications are exceptions when Do Not Disturb is turned on.


You can choose the amount of time to focus and start Focus directly from the Notification Center. When you start a focus session, the taskbar badge will turn off, the blinking of apps in the taskbar will turn off, a focus timer will appear on the screen, and Do Not Disturb mode will turn on.

Focus is integrated with the focus session in the Clock app, so you can play calming music and see a list of tasks from Microsoft To-Do. When your focus session ends, you'll receive a notification letting you know that your focus time is complete.


Redesigned Task Manager

Microsoft has updated the design of Task Manager with a new navigation bar and a new settings page to match the new Windows 11 design style. Each page now has a new command bar to access frequently used actions. Microsoft has also brought a dark theme to Task Manager and will automatically match the system-wide theme configured in the Settings app.

Microsoft also brings back the Eco mode under a new name Efficiency mode. When you notice that an app is consuming a lot of resources, you can right-click the process and apply efficiency mode to limit its consumption so that the system gives priority to other applications.

If the option is grayed out, this usually means that it is a core Windows process and throttling it may affect system performance. Processes in efficiency mode will be marked with a new green leaf icon, and Microsoft has also introduced a new pause icon for suspended processes.

Your Phone App

Microsoft has announced another feature for the Your Phone app. For those of you with Samsung devices, you can now enjoy more continuity in the process of moving from your phone to your computer. With this latest feature, you can easily access apps on your recently used Android device on your Windows PC.

Improved Quick Access

Microsoft is making updates to the Quick Access view of File Explorer. First, the support for "Pin to Quick access" has been extended from folders to files. Pinned files are displayed above the most recent files in Quick Access. And for users logged into Windows with a Microsoft account, pinned and recent files will also be displayed in Quick Access.

View OneDrive Storage in File Explorer

To help control storage consumption and ensure file synchronization, Microsoft has added OneDrive integration to File Explorer. When browsing OneDrive folders, you can now see sync status and quota usage.

New Touch Gestures

This release includes 5 new touch gestures that make it easier for users to navigate Windows 11 with touch on a PC.

Better Snap Layout

Microsoft has added a new way to snap windows into the Snap multitasking layout that works well on both touch and mouse. Simply drag a window to the top of the screen to display the Snap multitasking layout, place the window on top of an area to Snap multitask to line it up, and then use Snap multitasking assistance to complete the layout. In addition, Microsoft has improved Snap Multitasking Assist so that it works seamlessly between zones in the layout.

Better Power and Battery Options

The default values for the Sleep and Screen off have been updated to reduce energy consumption and carbon emissions when the PC is idle. Microsoft will also provide energy-saving recommendations to help reduce carbon emissions for those who set Sleep and Screen off to Never.

more power battery options

Improved Narrator in Microsoft Edge

Microsoft has made more improvements to Narrator and Microsoft Edge based on Build 22509.

While browsing a web page, you can have Narrator read the current item, and when you need to sort the tables on the web page, Narrator will announce the sort order you choose. When you encounter a dialog box on a web page, Narrator will help you stay focused in the dialog box and prevent navigation to the content behind it. This improvement is currently available in the Microsoft Edge Canary build.

Finally, Narrator has a few improvements when you are editing text on the Web. First, if you delete text on a form field, Narrator will read the deleted characters, and if you need to cut a large group of text with Control + X, Narrator will confirm that the text has been cut.

Other Updates and Improvements in Windows 11 Build 22557
