Windows 10 build 21286

Windows 10 build 21286 is the second Insider Preview build of Cobalt, the 21H2 development semester of Windows as a service. This build was released on 6 January 2021 to all Windows Insiders on the Dev Channel.

Changes
"Some of these changes were only available to a small group of Insiders, meaning that not everyone was seeing them right out of the box. They're completely rolled out to all Windows Insiders on the Dev Channel starting with build 21359."
 * A new flyout named News and interests has been added to the taskbar, which allows quick access to an integrated feed of dynamic content such as news and weather.
 * This feature would be later backported to consumer releases with 21H1 and 20H2 builds 19043 and 19042.962, respectively.
 * Storage Spaces can now be managed on Settings → System → Storage. However, the Control Panel page is still available.
 * Windows Subsystem for Linux 2 distros can now be configured to run any specified Linux command at startup. This can be accomplished by editing the  file in the distribution and adding an option titled   under a section titled.
 * Some updates have been done for users that have configured the time zone to be set automatically in Settings → Time and Language → Date & time:
 * When the time zone is updated due to a high confidence detected location change, a notification will appear informing the user about it. The toast will include information about the new time zone and clicking it will open the aforementioned page in Settings.
 * If a low confidence location change is detected and there is a single administrator on the device, a notification will appear asking the user to update the time zone, and clicking the OK option will apply the change.
