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

 * Updated the Start menu to inlcude theme-aware tiles, removed the solid color backplates and added a translucent background to the tiles. This update is only available to some Windows Insiders.
 * Tabs the user has got open in Microsoft Edge now show up in ALT+TAB. This feature is only available to a subset of Windows Insiders. It 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. 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 enhanced Alt+Tab 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 Start menu
If the theme-aware Start menu is disabled by default, you can enable it through the Vibranium Velocity (Vive) tool:


 * 1) Download the ZIP containing the tool from this GitHub repository.
 * 2) Launch the tool from a Command Prompt window.
 * 3) Type the following command:.
 * 4) Close the Command Prompt window.
 * 5) Restart your machine.

After restart, the new design of the Start menu should be enabled. However, this feature configuration uses to revert after several restarts, but it can also revert while the computer is in use.

Alternative toast experience
There is a rare combination on the A/B test of the new features in this build, in which most of them were by default hidden except the new toasts experience. If this occurred, a slightly different toast design would be used, in which the visible app logo and the new ellipsis for the Options menu were retained, but the arrow for dismissing the toast from the old design was still used instead of the new X. This quirk existed during the feature quality test and disappeared with its ending on build 20180, in which the appropiate design was coded into those machines that didn't had it before.

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.
