Microsoft has introduced a new command line interface for the Microsoft Store, accessible through PowerShell by typing "store." Users must have all current Windows 11 updates installed for functionality. The interface features ASCII art and a list of sub-commands, allowing users to search, install, and update software with minimal keystrokes. Users can install applications without needing to remember exact names, and commands like "store install firefox" yield accurate results. Limitations include the inability to install applications not available in the Microsoft Store. Users can also search for apps, gain insights into specific applications, and browse categories. The command "store updates" allows users to manage application updates efficiently.
