Windows Run, accessed via the Win + R shortcut, is being tested for a modern design update in newer preview builds of Windows 11. The updated version features a slimmer design similar to a floating search bar, with a new 'Run' icon and a centered text field. This modern variant will be optional, allowing users to switch back to the classic version if desired. Microsoft is also exploring additional advanced features for the modern Run dialog, which maintains comparable performance to the legacy version.
