user mode

Within the Windows 2000 architecture, user

mode is referred to as a less privileged processor

mode because it does not have direct access to

hardware. Applications and their subsystems run

in user mode. User mode applications are limited

to assigned memory address spaces and can’t

directly access other memory address spaces.

User mode uses specific application

programming interfaces (API’s) to request system

services from a kernel mode component.
