The command that is critical for application mapping in Windows discovery is netstat. This command is essential because it provides detailed information about network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. Specifically, when mapping applications, understanding the network connections that an application uses is crucial to comprehensively documenting how applications interact with each other and with the network.

Netstat helps identify which applications are listening on which ports, which is vital information when trying to establish service dependencies and interactions. This data can be used to construct an accurate service map, reflecting the relationships and communications between various applications and components in the system.

Other commands, while useful in different contexts, do not provide the specific networking information required for application mapping in Windows. For instance, ls is used primarily in Unix/Linux environments for listing files and directories, ps shows current active processes, and top provides a dynamic view of system processes. None of these commands offer the same level of insight into networking details that netstat does.
