On the command line console, enter netstat-ano.

Find the process that occupies port 5037 in the Local Address and write down the corresponding PID

On the command line console, enter the pid Number corresponding to tasklist/fi "PID eq, and write down the corresponding process name, end the process in the Task Manager (where the adb process normally occupies port 5037)
