Windows 10 build 20161

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

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. They're completely enabled on both upgrades and clean installations since build 20211.1000."


 * Start 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 icons now.
 * The icon for app folders has been updated, and it follows the Fluent Design system.


 * Open tabs in Microsoft Edge are now shown individually in Alt + Tab instead of just the Edge windows. This feature requires Microsoft Edge versions 83 or higher.
 * A more personalized taskbar for new users.
 * Notification experience updates:
 * 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 back to the previous behavior in Settings → System → Focus Assist.
 * Updates to Settings → System → About:
 * Information and links from Control Panel's System page have been fully migrated to Settings. Links that previously opened Control Panel now redirect to Settings.
 * 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 Update and Security → Windows Security page.
 * Windows and device specifications can now be copied to the clipboard via buttons on each section.
 * 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 the May 2020 Update.
 * The "Tablet mode" page under Settings → System has been renamed to simply "Tablet."
 * 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.
 * Other changes:
 * Both the Alarms & Clock and Paint 3D apps now require updates to be installed before they can be started.
 * Paint 3D's icon has been updated, resembling a multicolored teardrop shape.

In consumer releases
On 20 October 2020, the Windows 10 October 2020 Update was released to consumers, which during development was endowed with most features present in this build alongside another one from build 20175.1000. In addition, another cumulative update for those running the May 2020 Update was released with the new Start menu tile design and notification enhancements hidden under a Registry tweak.

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 can sometimes 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.
 * At the time of release, the update process had a chance of hanging for extended periods of time when attempting to install this build.
 * Notepad may fail to open files which were automatically saved during a PC upgrade (or restart if enabled in Settings). Saved documents can be recovered from.
 * Task Manager has a chance of showing a CPU speed of 0.00 GHz on the Performance tab. When Task Manager does not show 0.00 Ghz it may also sometimes 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 on this build.

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.
