Microsoft's updated Photos app is now available for Windows 11 in the Windows Insider Program, bringing requested interface changes and better image quality.

One of the most visible changes is support for actions like "Share" and "Start slideshow" on the main screen. Previously, these options were hidden in the menu, but Microsoft is exposing these toggles via the menu as it wants more people to use the features.
