Windows 10 build 20175.1000

Windows 10 build 20175.1000 is the fifth 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 22 July 2020.

Changes

 * Improved quick access to tabs for pinned sites in Microsoft Edge. Clicking on a pinned site on the taskbar now shows you all of the open tabs for that site on any Microsoft Edge window. This feature is only available to a subset of Windows Insiders and requires versions 85 or higher of the browser. It would also be delivered to customers with the Windows 10 October 2020 Update.
 * Introduced a new command in PowerShell: . This command allows users to reset their UWP apps via the command line. An example syntax appears as follows:   It can also be used to reset system components that aren't available to select in the Settings app, such as the Start menu.

ADMX backed policies for MDM

 * Starting with this build, 647 new Mobile Device Management policies were added across 56 ADMX files to enable users to configure policies that are also supported through Group Policy. These contain such items such as App Compat, Event Forwarding, Servicing and Task Scheduler.

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.
 * The "close all windows" option in the taskbar sometimes doesn't close all of the open tabs.
 * 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 to a browser tab can sometimes move the previously active tab to the front of the Alt list.
 * Opening a WSL1 distro can give out the error "The I/O operation has been aborted because of either a thread exit or an application request".

Disk Management in Settings
In build 20197, a new Disk Management experience was added to the Settings app. While it's confirmed to be internally present as far as Manganese build 19603, this is the earliest released build to already have it implemented, although it is hidden. To enable it, download the Vibranium Velocity (Vive) tool, extract the contents from the ZIP file, launch the executable from an elevated Command Prompt window, enable the following ID, and restart:. After restarting, go to Settings → System → Storage → More storage settings, and you'll see a link that says "Manage Disks and Volumes," which you can use to access the page. At this point, it mostly appears to be finished like in the final experience.
