Changes

 * A new flyout named News and interests has been added to the taskbar.
 * 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.

News and interests

 * The flyout may show as offline even when the user is online.
 * Users cannot navigate into the news and interests flyout using keyboard.
 * In some scenarios, the flyout may appear empty with no content.
 * Sometimes the flyout cannot be dismissed with touch and pen.
