Windows 10 build 20190

Windows 10 build 20190 is the eighth Insider Preview build of Iron, the 21H1 development semester of Windows as a service. This build was released to Windows Insiders in the Dev Channel on 12 August 2020.

Changes

 * After installing a major Windows 10 feature update, you can now toggle an option in Settings that will notify you as to what changes have been made. This experience is only available for English-speaking countries.
 * Various improvements were made to the Graphics settings. Users can now pick a specific default high performance GPU, as well as updating it to allow them to pick a specific GPU on a per application basis.
 * An ability was added to choose exactly which GPU an app can be run on using a new “Specific GPU” option.
 * Updated the new Japanese IME to support switching between hiragana and katakana by using Ctrl and Alt respectively, like in previous versions of the IME.

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.
 * Performing an Alt + Tab to a browser tab can sometimes move the previously active tab to the front of the Alt + Tab list.
 * The letter headers on the all apps list on the Start menu have unnecessary left padding when the all apps list is set to hidden.
