Other insider updates

Android app streaming is available to all users

Microsoft is pleased to announce that the new feature of the “Your phone” app, which was announced on August 5 at the Samsung Unpacked event, is now available to all users. This feature allows you to instantly access mobile apps from your Android smartphone from your Windows 10 PC. You can conveniently pin your favourite apps to the taskbar or start menu for quick access to them.
Applications that you launch open in a separate window outside of the “Your phone” app, which allows you to perform multiple tasks simultaneously. If you need to respond quickly in a conversation or order bard, you can do this using the PC’s large screen, keyboard, mouse, pen, or touch screen, just like in other PC apps.

Requirements for the function:

  • We recommend that you always use the latest version of Windows 10, the “Your phone” app, and the “Connect with Windows” feature.
  • The app comes with communication with windows 2.0 version and phone version is 1.20071.88
  • Available on some Android smartphones running Android 9.0 or higher with Windows Connection integration. A list of supported smartphones can be found at this link.
  • Your PC and smartphone must be connected to the same Wi-Fi network.
  • The feature becomes available gradually, so it may take several days before you see it on your device.


  • Updated the Alt + Tab behaviour for Microsoft Edge tabs so that no more than 5 tabs are displayed in the menu by default, instead of all recent tabs. If you want to change this, you can always make a setting in Settings > System > Multitasking.
  • The company is considering including the Web Browsing section in The settings application header bar. In this build, some Insiders may see this change.
  • In the future, only the currently active image will be displayed next to your profile information in the “Settings” section.
  • Based on the feedback, we disable the ESENT warning with code 642 that appeared in “event Viewer”.
  • Now the new Microsoft Edge can be selected as the desired application in Assigned Assess.
  • Updated “Screen announcer”, so that now when using Microsoft Pinyin IME,” Screen announcer ” will be able to distinguish words and characters in sentences, providing detailed information for voicing.
