Starting from turning on the computer, many do not think about how the operating system is organized. It turns out that during boot, there is a change of processes, each of which cannot be thrown out of this chain.
Necessary
A computer with the Windows XP operating system installed
Instructions
Step 1
The operation of the system begins with its launch and loading all components. The whole complex of loading can be divided into 4 blocks of processes, the first of which is called "Initial phase of loading". This is where the processor transitions from normal to safe mode. initially you need to download the drivers for all file systems that Windows XP supports (NTFS, FAT16 and FAT32).
Step 2
The boot.ini file is then read. If it contains several lines, a menu with the corresponding number of operating systems will appear on the screen. This is only true for Windows-based systems. To select a specific boot type, the user presses the F8 key. This stage is referred to as the second process block "System Selection".
Step 3
The next block of processes is called Iron Detection. This is where the ntdetect.com file opens. The main function of this application is to detect the installed hardware, as well as read components from the Hardware key (HKEY_LOCAL_MACHINE registry branch). After that, the main Windows XP kernel is loaded, the files of which are located in the System32 directory.
Step 4
This is followed by downloading the drivers of all devices registered in the system during its installation. New devices are flagged in the registry and their software installation is delayed until the welcome screen appears.
Step 5
The last stage is "Choice of configuration". First, the smss.exe file opens, which is responsible for the User Accounts applet and the entire working interface. The same file gives the command to open the win32k.sys file, the main task of which is to start the graphics subsystem.
Step 6
The completion of the whole complex of these operations is the launch of the winlogon.exe file: a welcome window appears on the screen, where you need to select an account and enter a password (if any).
