The file netbios.sys is the NETBIOS interface driver for Microsoft Windows Operating System. This file type is a DLL file component that stores data about the device drivers, settings, and other Windows system information. Designed for the Windows Operating System, netbios.sys helps in executing DLL files by installing the library into the Windows system's memory. It is shared by many applications and Windows functions so it is necessary to keep this file intact. The NETBIOS (Network basis input/output system) is the program that allows applications on different computers to communicate within a local area network (LAN). NetBIOS communication modes can be either a session or a datagram mode. The session mode is used to establish a connection between two computers, wherin the "conversations" that ensue allow large messages to be handled, and provides error detection and recovery. In the datagram mode, there is no connection since each message is sent independently, and the messages must be smaller.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. netbios.sys. is used by Windows Operating System, If you shut down netbios.sys, it will likely start again at a later time either after you restart your computer or after an application start.

After uninstalling applications it is a good idea to scan you Windows registry for any left over traces of applications. Registry Reviver by ReviverSoft is a great tool for doing this.

A process usually a part of an installed application such as Windows Operating System, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.
