Windows XP is a safer operating system. You must select an account and enter a password each time you start Windows XP. It is safer for a public computer, but if this computer is used by one person, there is no important information. It is too difficult to select an account and enter a password every time. How can we enable Windows XP to automatically log on without entering a password?
Click Start/run and enterRundll32 netplwiz. dll, usersrundll", Press the Enter key and the" User Account "window will pop up. It is clear that this is different from the" User Account "panel window opened in" Control Panel! Then deselect"To use the local machine, you must enter the user name and password"Option, click OK. In the displayed dialog box, enter the account and password that you want your computer to automatically log on.
In fact, automatic logon can also be implemented in Windows 2000, but it can open the "User Account" window through the "control panel", but not in Windows XP.
