This is the central key-value store for all Windows programs, mostly storing configuration data. In this case Windows Explorer will consume the config data for displaying context menus on a folder. The key is "Default" and it will be executed. The value is cmd /K (run a command) cd %L (change to the directory handed over in the variable L) && (...
