What’s new in Build 22579

Exclude USB removable drives from encryption

We are introducing a new policy so that IT administrators can exclude USB removable drives from BitLocker encryption. This will solve the problem of automatic or accidental encryption of storage built into specialized devices like video cameras, voice recorders, conferencing systems, medical devices and many more. When this policy is enabled, you will not be able to encrypt storage that is on the exclusion list, and you will not be prompted for encryption if you connect such storage to a device while “Deny write access to removable drives not protected by BitLocker” policy is enabled on it. This policy so far can only be configured via MDM custom OMA-URI. Here are the steps an IT administrator can take to exclude storage from encryption: STEP 1: Gather Hardware IDs of devices you want to exclude. You can follow the steps to get hardware IDs of devices outlined here in this Docs page. STEP 2: Configure BitLocker Exclusion list Policy in Intune:
  1. Login to Endpoint Manager portal.
  2. Go To Devices > Configuration Profiles.
  3. Click "Create Profile".
  4. Select Platform "Windows 10 and later" and Profile type: “Templates” then select Template Name: “Custom”.

Changes and Improvements

  • As some Insiders noticed, along with our updated Print Queue experience, we have also made an update so that win32 apps which use CPrintDialog to display the print dialog will now show our modern print dialog. In addition, the modern print dialog discovers local network printers automatically. If you choose a new printer, it will be installed without you needing to go into Settings. Please file feedback about your printing experiences under Devices and Drivers > Print in the Feedback Hub.
  • We are reverting the Open With dialog box redesign that began rolling out with Build 22567 to the previous design. We plan to bring this back in the future after addressing some performance issues identified by Windows Insiders. Thank you for your feedback!
  • To ensure users are still able to quickly access the console if Windows Terminal has been uninstalled, we are updating the WIN + X menu to point to Windows PowerShell. If you have Windows Terminal installed and would like Windows PowerShell to open in Windows Terminal, we recommend going to Settings > Privacy & Security > For Developers, and setting Windows Terminal as your default terminal app.
  • Magnifier and the on-screen keyboard now have new Fluent-style icons.
[Start menu]
  • You can now name your folders of apps in Start. To name a folder, simply create a folder (which will have the default name of “Folder”), open it, click on “Edit name”, and type your folder name. Alternatively, use keyboard focus to open the folder then select the text box and start typing.
[caption id="attachment_175583" align="alignnone" width="617"]Folders on Start. Folders on Start.[/caption] [Get Started app]
  • We have added pinned site suggestions to the Get Started app so you can conveniently pin websites to your taskbar. To find this new feature, launch the Get Started app and navigate to the “Apps and sites we think you’ll love” page. Click on any of the sites suggested on the page to pin it to your taskbar so you can access the sites you care about in one-click. Please file feedback in the Feedback Hub (WIN + F) under Apps > Get Started.

Personalized site recommendations and other locales will be supported soon. [Windowing]
  • Continuing our effort to update multi-finger touch gestures to include responsive and delightful animations that follow your finger, try using three fingers to swipe left and right and switch between recently used windows.

NOTE: Some fixes noted here in Insider Preview builds from the active development branch may make their way into the servicing updates for the released version of Windows 11 that became generally available on October 5th, 2021.

Known issues

[Tablet-optimized taskbar]
  • The taskbar doesn’t always automatically collapse after launching an app or tapping outside of the expanded taskbar on 2-in-1 devices.
  • Some areas of the OS are not yet tracking the height of the expanded taskbar on 2-in-1 devices so you may see overlapping components, such as Widgets overlapping with the taskbar.
[File Explorer]
  • Opening suggested results shown while entering search terms in File Explorer's search box may not work.
  • We’re working fixing issues regarding icon sizing, visual bugs, and text clipping in the flyout showing OneDrive storage.
  • Sometimes when pinning from the Feed, the pinned widget is placed at the top instead of below other pinned widgets. If this happens this will autocorrect within 30 minutes, moving the recently pinned widget to the expected default location. Or you can sign out of your Widgets board and immediately signing back in should correct the problem.
  • After rearranging widgets in the widgets board, some users experience problems with widgets in the pinned section rendering incorrectly. If this happens, signing out of your widgets board and immediately signing back in should correct the problem.
  • The Clock app does not yet update Windows Focus state when configuring focus sessions within the app. This will be addressed in a future app update.
  • Natural voices are breaking up sporadically in the latest build. Restart Narrator to resolve the issue.
[Live captions]
  • Certain apps in full screen (e.g., video players) prevent live captions from being visible.
  • Certain apps positioned near the top of the screen and closed before live captions is run will re-launch behind the live captions window positioned at top. Use the system menu (ALT + Spacebar) while the app has focus to move the app’s window further down.
  • The very top of maximized apps (e.g., title bar window management buttons) can’t be reached with touch while live captions is positioned at the top.
[Task Manager]
  • Some tooltips do not accurately display the preferred visual setting when Task Manager is configured for dark mode.

Your Phone app – Recent Apps Feature: continuity with your office documents

We recently announced the Recent Apps feature which allows you to easily access the three most recently used apps from your Android device on your PC. Now, we are excited to introduce the latest integration of Your Phone and Office mobile expanding the Office productivity with your Samsung device. [caption id="attachment_175587" align="alignnone" width="607"]You can open the supported documents in your Office desktop app or browser and pick up right where you left off on your phone. You can open the supported documents in your Office desktop app or browser and pick up right where you left off on your phone.[/caption] You were able to access your Office documents on the go with the Office mobile app, but now with Your Phone’s deeper integration with Office, when you get back to your PC, you can open the supported documents in the Office desktop app or browser and pick up right where you left off on your phone. Simply click on the document icon from your Recent Apps flyout from Your Phone icon in the system tray on the taskbar or from within the Apps page in Your Phone app and continue working without missing a beat. The feature is gradually rolling out to Windows Insiders on select Samsung devices (details below). Try out the feature and let us know what you think! FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Apps > Your Phone. Recent Apps – Office continuity requirements: To use this feature, you will need:
  • Your Phone app version 1.22022.60.0 or higher. Older versions will not show recent apps even if you have a supported device.
  • Office mobile app version 16.0.14931.20106 or higher.
  • A supported Android device. Recent Apps requires a deeper level of integration with the Android device and the team worked directly with Samsung to light this up. It is available on select Samsung devices that have Link to Windows, with OneUI 3.1.1 or higher and Link to Windows Service 2.3 or higher, such as:
    • Samsung Galaxy Z Fold
    • Samsung Galaxy Z Flip
    • Samsung Galaxy S series
    • Samsung Galaxy Note series
  • Your Android device and PC need to be connected to the same Wi-Fi network for apps to launch on your PC.
Supported Office Documents: Word, Excel, PowerPoint documents saved in OneDrive

About the Dev Channel [Updated!]

The Dev Channel receives builds that represent long lead work from our engineers with features and experiences that may never get released as we try out different concepts and get feedback. It is important to remember that the builds we release to the Dev Channel should not be seen as matched to any specific release of Windows and the features included may change over time, be removed, or replaced in Insider builds or may never be released beyond Windows Insiders to general customers. For more information, please read this blog post about how we plan to use the Dev Channel to incubate new ideas, work on long lead items, and control the states of individual features. These aren’t always stable builds, and sometimes you will see issues that block key activities or require workarounds. It is important to make sure you read the known issues listed in our blog posts as we document many of these issues with each flight. Build numbers are higher in the Dev Channel than the Windows 11 preview builds in the Beta and Release Preview Channels. You will not be able to switch from the Dev Channel to the Beta or Release Preview Channels without doing a clean install back to the released version of Windows 11 currently. The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.
