Windows 10 build 20197

Windows 10 build 20197 is the ninth Insider Preview build of Iron. This build was released to Windows Insiders in the Dev Channel on 21 August 2020.

Changes

 * The Disk Management experience in the Settings app was officially enabled. It was internally present since Manganese build 19603, but it wasn't implemented until build 20175.1000 as a hidden change that had to be turned on via Vibranium Velocity (ViVeTool).
 * A new Startup App Notification has been added, which informs users about apps that register to automatically run at login.
 * The new post-update experience with the Tips app was dropped from this build onwards (this feature was a trial run, exclusively only in build 20190).
 * Updated the Alt + Tab behavior with Microsoft Edge tabs to display five tabs by default rather than any recent tabs. The settings for this can be changed by navigating to Settings → System → Multitasking.
 * A web browsing section on the Settings header was rolled out to some Windows Insiders.
 * ESENT Warning Event ID 642 errors are no longer logged in Event Viewer.
 * The Chromium-based Microsoft Edge can now be chosen as an Assigned Access app.
 * Updated Narrator, so when the Microsoft Pinyin IME is being used, Narrator can now distinguish candidate characters and/or words by providing detailed reading information.

Bugs and quirks

 * Some Microsoft Store games protected with Easy Anti-Cheat may fail to launch.
 * The update process to this build has a chance of hanging for extended periods of time.
 * The minimize, maximize, and close buttons can get stuck in their original positions if you resize a UWP app. A workaround is to move the window.
 * Some pinned websites do not work with the new taskbar experience.
 * Live preview doesn't work for pinned site tabs.
 * Pinned sites don't show all open tabs for a domain. A workaround with this issue is to pin the site’s home page rather than a specific page.
