Windows 10 October 2020 Update

Windows 10 October 2020 Update is an update to Windows 10 which was released on 20 October 2020.

New features and changes
Some of the features introduced in this version have been backported from builds 20161 and 20175 from the Iron development cycle, as well as 21286 from the Cobalt cycle.

Start menu improvements

 * Tiles for pinned apps no longer have an accent color. Instead, they are now theme-aware and can be white or black depending on the system theme. If transparency effects are enabled, they will also have an acrylic transparency.


 * Apps on the apps pane no longer have their icons displayed under an accent-colored backplate. They only show the icon now.

Microsoft Edge updates

 * The legacy Microsoft Edge is now hidden in the system by default, with the Chromium version being now an inbox app in its place. Later updates would eventually remove it entirely.
 * Open tabs are now shown individually in Alt + Tab instead of just the browser windows.
 * Clicking a pinned site on the taskbar now shows all open tabs for it across any browser window.

Notification and Focus assist changes

 * The overall design of notification toasts has been changed to resemble that of Windows 10X. On the upper border, the app logo and name are now displayed so that users can easily identify which app generated a toast. Additionally, the icons for toast settings and dismissing to action center have been changed from a gear and an arrow to an ellipsis and an X.
 * The summary and automated rule enablement notifications for Focus Assist are now disabled by default. This can be reverted to the previous behavior in Settings → System → Focus assist.

Settings changes

 * Information and links from Control Panel's System page have been fully migrated to Settings → System → About, and links that previously opened the Control Panel page now open the Settings counterpart. In addition, Windows and device specifications now copyable via buttons on each section.
 * Security status data has been consolidated. While summary messages are still shown, the rest of the details have been removed, and they can be queried on the Windows Security page under the Update and Security section.
 * The "Tablet mode" page under the System section has been renamed to simply "Tablet".
 * When going to Settings → System → Display → Advanced display settings, there is now an option to change your displays' refresh rate without having to open the legacy Monitor Properties dialog.

Tablet experience enhancements

 * The notification toast that previously asked 2-in-1 users to switch to tablet mode when detaching the keyboard has been removed. Now, when this action occurs Windows will simply switch to the new tablet experience from May 2020 Update build 19041.329.
 * The quick action for Tablet mode is now automatically removed from the Action Center on non-touch devices to prevent confusions.
 * A new logic is incorporated to let users boot into the appropriate mode according to the mode they were last in and whether the keyboard is attached or not.

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. This feature is available starting with builds 19042.962 for Windows Insiders and 19042.964 for consumers.

Other changes

 * Programmable Taskbar has been added, which allows to provide a customized default taskbar layout in new user accounts, depending on the different scenarios present in their Microsoft account linking experiences.
 * The new Modern Device Management (MDM) Local Users and Groups policy allows an administrator to make granular changes to a local group on a managed device, on par with what has been available to devices managed with on-prem Group Policy (GP).

Version numbering
This version drops the YYMM numbering scheme, introduced with the November Update, in favor of the half-year based YYHx scheme already used previously for codenames since the Windows 10 May 2019 Update. However, the former scheme is still in use, and is "Version 2009" as seen in the  Registry key in order to keep compatibility with some applications. Later versions still contain the key with the same value.
