Windows XP is said to be the most secure operating system, it is said to be an invulnerable operating system. 80% of the computer users in this world use Windows XP. Microsoft has said that Windows XP has will help you to have a safe and secure computing experience.

Okay, after you get a Windows XP bootable CD, place it in your CD ROM or CD Re-Writer, now boot your computer through CD.

In Windows XP, during the splash screen, press F4 and then choose boot from CD.

Now, you will see a message on the screen saying that
“Press any key to boot from CD”

Once you get into the setup, you will observe that setup is inspecting your system and loading setup files. Once you get the Welcome to Setup screen, press ENTER to setup windows. The Licensing Agreement will be displayed next press F8 to agree it. The next screen will give you an option to do a repair. You will see that “If one of the following Windows XP installations is damaged, Setup can try to repair it”

During the reboot, do not press any key to continue because if you do then the normal boot up process will start.

You can also stop the password prompt, for this you must follow the same procedure given above. But, only one thing you have to change, in the command prompt type in control userpassword2, a screen will popup, choose log on without being asked for the password.
