Windows 10 build 21286 is the second Insider Preview build of Cobalt, the 21H2 development semester of Windows as a service. It was released to the Windows Insiders in the Dev Channel on 6 January 2021.
== New features and changes ==
=== User interface ===
==== News and interests ====
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. It would be later backported to consumer releases with the May 2021 Update, October 2020 Update and May 2020 Update builds 19043, 19042.962 and 19041.962 respectively. 
This feature is only available to a subset of users, but can be activated manually by having Chromium-based Microsoft Edge installed, have the system region set to United States, Canada, United Kingdom, Australia, or India, and then enabling Velocity staging keys 29947361, 27833282, 27368843, 28247353, 27371092, 27371152, 30803283 and 30213886.

A notification will appear that inform users regarding high confidence detected location changes if the time zone is set automatically. Additionally, it will also appear if a low confidence location change is detected, asking the user to update the time zone.
== Bugs and quirks ==
=== 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.
* The flyout uses more taskbar space on the left than expected.
=== General ===
* The update process to this build has a chance of hanging for extended periods of time.
* Some rendering or graphic issues may be experienced after resizing certain app windows. This should be resolved after minimizing and restoring all windows by using the hotkey twice.
* Some 32-bit systems may lose network connection after upgrading to this build.
* When Xbox Game Bar is launched from the Start menu or via the hotkey while using a text editor, the computer may appear unresponsive. If the user encounter this, dismiss the bar with the same hotkey and end the GameBar.exe process from Task Manager.
* File Explorer might hang or crash in this build.
* Live preview doesn't work for pinned site tabs on some machines, a gray window is seen instead of the intended content.
