In the case of XP system running normally, there are a lot of system processes to support the operation of the xp operating system, these are the main processes of the xp system, but many friends do not understand what the process is? A process is the basis of the operating system structure; it is the execution of a program; it is the activity of a program and its data when it is executed sequentially on the processor. It is more ambiguous to say that the process is an active subroutine in the application resident memory. Any application has a process active while the program is running, and the operating system is no exception.
