Windows 10 KB5001391 (Build 19042.964) Full Changelog

With this update, Microsoft is finally introducing the Google Discover-like news and weather feed for the Windows taskbar.

As you may know already, the Windows taskbar hasn’t changed at all in the last three years.

After beta testing, the “News and Interests” feed is now coming to Windows 10 version 20H2 and version 2004. As you see in the below screenshot, the taskbar feed would be enabled by default and it’ll show weather information with sky conditions, news and personalized stories.

Windows 10 Build 19042.964 also comes with additional bug fixes for everyone. For example, Microsoft has fixed an issue where a device unexpectedly fails security tests in organizations.

Another bug has been fixed where Windows 10 in S Mode stops working properly.

Likewise, a rare bug that causes issues with lsass.exe has been fixed. For those unaware, LSASS refers to the Local Security Authority Process, a process that is responsible for login and authentication on Windows 10.

Windows 10 Build 19042.964 also comes with these improvements:

  • Mixed reality users can now adjust the amount of idle time before a headset goes to sleep.

  • Microsoft is aware of issues with Input Method Editor (IME) and is working on another patch.
