Windows XP launches automatically as your computer starts up. After you get past the Windows Welcome screen, you're taken directly to the Windows desktop and your system is ready to run.
When the Windows Welcome screen appears, click your username or picture.
Enter your password (if necessary).
Press the Enter key on your keyboard or click the green right-arrow button.
TIP
Single-User Systems
If you have only a single user on your PC and that user doesn't have a password assigned, Windows moves past the Welcome screen with no action necessary on your part.
