How can I see running ports on Windows 11?

I need to see port:8080 is running or not. And I tried: netstat -a -b

and it returned error message "The requested operation requires elevation."

There's a native GUI for Windows:

• Start menu → All Programs → Accessories → System Tools → Resource Monitor

• or run resmon.exe,

• or from TaskManager → Performance tab.

You can see details in this answer.
