network port usage app

Description of the new feature / enhancement

A new PowerToy to see which programs are using each network port. Equivalent to File Locksmith but for networking.

It should show the following items for each open socket:

• Program name
• Program path
• Process ID
• Process owner
• Protocol (UDP/TCP)
• Port Number
• Status (Listening, Established, ...)
• Attached interface (127.0.0.1, ...)

Scenario when this would be used?

• When programming, it is common to have some process already using a TCP/UDP port and blocking its usage.
• When checking which port an undocumented program is using (reverse engineering, debugging)

Supporting information

This is already possible via cmd and PowerShell. Requires privileges.
