Which command displays a list of applications and services with their Process ID (PID) on a computer?

The command that displays a list of applications and services with their Process ID (PID) on a computer is "tasklist." When used with the "/v" option, it provides detailed information, including the process ID, session name, session number, memory usage, and the status of each application. This in-depth view allows a user to not only see the running processes but also gather additional details that may aid in troubleshooting or monitoring system performance.

The other options have specific purposes. For instance, "/s" typically interacts with a remote system, "/u" specifies a user account for accessing a remote system, and "/p" is intended to run the command with a specified password for remote connections. These options do not enhance the basic listing provided by "tasklist" to include the detailed information that "/v" offers, thereby making the correct answer the one that enhances the visibility of processes significantly with added details.
