If you are using Windows Xp and want to get rid of the blue "Welcome" screen that shows up at startup (prompting you to select the correct user account and enter the password, if any), then this post can be useful :-) One reason for turning off this feature is that you can turn on your PC, and come back after some minutes and you are right on the desktop (ready for use). However, please bear in mind that although you are the sole user of the system, it is not recommended to do so as it simply means you are disabling the basic security feature that the operating system provides. So, be careful!
You have currently logged on windows as Administrator and have admin rights.
1. Click Start and then select Run,
2. In the Run window, type control userpasswords2, and then click OK button,
A User Accounts windows pops up.
3. Clear the "Users must enter a user name and password to use this computer" check box, and then click Apply.
You will be requested for the username and password of the account you wish to automatically logon as for following reoots of your system.
4. In the Automatically Log On window, type the required information and click OK to close the window.
5. Finally click OK to close the User Accounts window.
At any later stage, you can activate this security feature by following the same steps but recheck the box, at step 3.
