We finally have a new version of WinDbg that is available outside of the Microsoft Store, and as an added bonus that Preview label is gone. This release also represents a welcome update to the UX architecture, to what I assume is WPF.
This latest version features a more modern user experience with an updated interface, fully fledged scripting capabilities, an extensible debugging data model, built-in Time Travel Debugging (TTD) support, and many additional features.
To get and stay on the latest release, install WinDbg as described here. The version of WinDbg available from the Microsoft Store will no longer be updated.
One more hidden gem, this version officially supports Arm64!
