... I came to this action. Copy and save it in a .bat file:
FOR /F "usebackq tokens=5" %%i IN (`netstat -aon ^| find "3306"`) DO taskkill /F /PID %%i
Change 'find "3306"' in the port number which needs to be free. Then run the file as administrator. It will kill all the processes running on this por...

Unmangling the result of std::type_info::name
