All it does is run the command every minute forever. So in theory you should add a scheduled task that will run every minute forever in the windows scheduler. The command should probably be something among the lines of:
C:\path\to\php C:\path-to-your-project\artisan schedule:run
However i have never tried doing this under windows.
Edit: you should probably set it to 'Run in' the 'C:\path-to-your-project' folder too just to be sure everything works as expected (even though the paths are in the command itself).
