Microsoft has released a new version of WinDbg, the Windows debugging tool that is very popular among Windows developers and administrators who work on troubleshooting and debugging.

The new WinDbg is currently under development and only select users running Windows 10 Anniversary Update can install it from the Windows Store.
Microsoft hasn't updated WinDbg in years, and yesterday's release came as a surprise to most users. The new Preview version includes two new features and UI-related changes.
The new tool features a completely revamped UI, which now uses the classic "Ribbon UI" as a way to display menus and buttons, offering a simpler user experience, similar to the use of other Ribbon-based applications, such as Office, Explorer, Outlook, and others.
You can try and see if you are selected to install the new Preview tool WinDbg from this Window Store page. You can also download and install the current stable version from here.
Before installing the Preview version, just remember that you are dealing with a tool that is still in development. If you are not willing to deal with WinDbg bugs, it is better to wait until the stable version is released.
