How to check open ports on Windows

“Open ports” usually means listening sockets, not every ephemeral connection.

PortPilot

Install the Windows agent, then:

• Desktop Ports
• portpilot ports
• Website Ports after pairing

Each row includes protocol, bind address, port, process, and health.

netstat

netstat -ano | findstr LISTENING

Use PortPilot when you also want health layers, history, and controls.
