Changes[edit | edit source]

The Snip & Sketch app has received an update, which brings with it some changes along with a new icon.
Editing your DNS server assignment is now a top-level option when you go into your network's properties page.
You can now configure Encrypted DNS (DNS over HTTPS) directly from the Settings app.
The 3D Viewer app has been moved to the Windows Accessories folder on the Start menu.

Bugs and quirks[edit | edit source]

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 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+Tab ↹ to a browser tab can sometimes move the previously active tab to the front of the Alt+Tab ↹ 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".
