Windows 10 build 20161

Windows 10 build 20161 is the third Insider Preview build of Iron. It was released on 1 July 2020 to Windows Insiders that are on the Dev Channel.

Changes
"These changes were only available to a small group of Insiders at first, meaning that not everyone was seeing them right out of the box. As of build 20180, they are available for all Dev Channel Insiders."


 * Updated the Start menu to inlcude theme-aware tiles, removed the solid color backplates and added a translucent background to the tiles.
 * Tabs the user has got open in Microsoft Edge now show up in ALT+TAB. This feature requires a Canary or Dev build of Edge.
 * A more personalized taskbar for new users.
 * Improved notification toasts.
 * Migrated the information in the System section of Control Panel to the Settings app. Links in Control Panel that would take you to the System section now take you to the Settings app.
 * You can now copy your device information in Settings.
 * Notification that asks the user if they want to switch to tablet mode now no longer appears when you switch to said mode on 2-in-1 PCs.

In the Beta and Stable Channels
On 24 July 2020, Microsoft released build 19042.421 of version 20H2, which brought all of this changes to the Beta Channel together with one of the features of build 20175.1000. Later, cumulative update 19041.423 was released as an optional update to consumers with the May 2020 Update, in which users could enable the theme-aware Start menu and the new toast experience through a Registry tweak. This is something expected due to the fact that versions 2004 and 20H2 share mostly the same code and servicing, meaning that the modified values can be ported from one to another.

Enabling the new features
If the new features are disabled by default, you can enable them through the Vibranium Velocity (Vive) tool. To do it, download the ZIP containing the tool from this GitHub repository, extract the files and launch the executable from an elevated Command Prompt window. Once you run the executable, type the following commands:

After typing the commands, restart the computer to see the new features enabled. However, they use to revert randomly after several restarts, but they can also revert while the computer is in use.

Bugs and quirks

 * There's a chance that the system may crash with a  BSOD.
 * Notepad may fail to open files which were automatically saved during a PC upgrade (or restart if enabled in Settings). Documents can be recovered from.
 * Task Manager may show a CPU speed of 0.00 GHz on the Performance tab. When Task Manager does not show 0.00Ghz it may also show abnormally high values.
 * In certain apps, if you press space while using the Korean IME, the last character is deleted.
 * You might see flashes of color during the tile animations on the Start menu.
 * The setting under Settings - System - Multitasking to set ALT+TAB to "Open windows only" does not work in this build.

Features disablement
Starting with this build, there are some scenarios such as resetting your PC where the new features might become disabled, reappearing the accent-colored Start menu tiles, old-designed toasts, System section in Control Panel, and removing individual tabs from Alt+Tab. Usually, they recover after some time using the PC, but if this doesn't occur, update your computer or use Vibranium Velocity.

Alternative toasts experience
If many of the new features, except the new toasts experience, were disabled by default on your PC, a rare condition would appear in which not all of the improvements made would be visible, since the new X for dismissing toasts to the Action Center is not present, and the arrow from the older design is used in place.
