Getting the parameters of a running JVM

Windows 10 or Windows Server 2016 provide such information in their standard task manager. A rare case for production, but if the target JVM is running on Windows, the simplest way to see its parameters is to press Ctrl+Alt+Delete, choose the Processes tab and add the Command line column (by clicking the right mouse button on any existing column header).
