Microsoft is testing a new version of the Run command window (summoned by pressing Win + R simultaneously) in Windows 11.
The new version is based on Microsoft’s Fluent Design ethos, which infuses Windows apps and tools with a more modern look with rounded corners and support for the dark mode in Windows 11.
For now, it seems that users will be able to choose whether they want to run the new or the old version, via an option in the advanced system settings. If you want a peek at the new design and how it contrasts with the original, check out Windows Latest’s full report on the new Run.

The old version of Windows Run has basically remained unchanged since the Windows 95 era, which means that the code is currently more than 30 years old.
