Windows 10 build 19645

Windows 10 build 19645 is the twenty-second Insider Preview build of Manganese. It was released to Windows Insiders in the Fast Ring on 10 June 2020 as the final build from this development cycle, since the next build moved builds on the then-renamed Dev Channel to the Iron cycle.

Changes

 * Changed the servicing model for WSL2 distros. As a result of this change, the Linux kernel was removed from the Windows image. From this build onwards, it is now serviced via Windows Update in a similar matter to how third-party drivers like graphics and touchpad devices are installed and updated.
 * Added support for nested virtualization on AMD processors.

Bugs and quirks

 * At the time of release, the update process had a chance of hanging for extended periods of time when attempting to install this build.
 * Both the documents and downloads sections in the privacy settings have broken icons, and as such, rectangles show up where the icons are intended to be instead.
