                       Procedure for Starting a Computer


              When the power button is switched on, Windows 11 follows the given Start up Process:
              •  The system performs Power-On-Self-Test (POST) to check that all the hardware devices are functioning properly
                with constant supply of the electricity. In case there is any error, a beep sound is produced, an error message is
                displayed on the screen and the system stops loading windows. You might see the manufacturer's logo on the
                screen during this process.
              •  The computer's BIOS initialises and looks for the bootloader on the primary storage device. The bootloader
                (usually Windows Boot Manager) is executed and it starts loading Windows 11 into the computer’s memory
                (RAM).
              •  After this, you will see Windows 11 logo and the Operating System will take over the whole process of
                controlling and configuring the system where Windows 11 kernel initialises the system’s hardware and loads
                necessary drivers.
              •  After the system configuration is done, System Utilities and Antivirus will become active to participate till the
                system is on.
              •  Session Manager will take over and the system is ready for the authentication process to display the user name
                and password screen.
              •  If the valid credentials are is entered, Windows 11 loads your user profile, including desktop settings, preferences,
                and startup applications.  Finally, the computer is ready to use.
