Windows 11 is drawing inspiration from PowerToys utilities
The Windows 11 development team and the one behind PowerToys are entirely separate entities, but it seems like one is being inspired by the other.
While the PowerToys utilities exist to improve on the features found in Windows -- as well as adding completely new options -- sometimes the utilities collection has an influence on the operating system. A good case in point is the new microphone-muting keyboard shortcut that has just been added to the latest builds of Windows 11.
