WinDbg Preview is a new version of WinDbg with more modern visuals, faster windows, and a full-fledged scripting experience. It is built with the extensible object-orientated debugger data model front and center. WinDbg Preview is using the same underlying engine as WinDbg today, so all the commands, extensions, and workflows still work as they did before.
