Windows version 2000 DMI Call Kernel Driver is the service name of the driver file dmicall.sys, and is a part of the program Sony DMI Call Service, or Windows 2000 DMI Call Kernel Driver, which is developed by Sony Corporation. This driver process has a digital signature (Microsoft Time-Stamping Service) from Microsoft Windows Component Publisher, and makes it a legitimate file, which means it must not be terminated or stopped, but rather continuously run in the background of a computer system. Because it is digitally signed, it is more recommended to keep it stored and actively running as a background process. This kind of file is compatible with Microsoft Windows Operating System, which is a well-known software product developed by Microsoft Corporation, but this only works on a certain OS, and that is Windows OS. In addition, this file may only be deleted or stopped, when it is causing errors or problems that affect the performance of the system.
