Simple three-step modification to achieve automatic login of XP system

Before entering the Windows XP desktop, every time there will be a brain login interface, asking us to enter the username and password, which can increase the security of the system. It also provides convenience for many people to share a computer, but if it is a home computer, only you can use it alone, so each time the password is not a little convenient. We can achieve automatic login of XP by modifying the registry.
Step 1: Run the Registry Editor, expand the [HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon] branch, then double-click "DefaultUserName" in the right window and enter your login username. If there is no default user name, you can add this item by selecting “edit →new →string value(s)→DefaultUserName” in the menu bar of the Registry Editor. Note that you should distinguish between uppercase and lowercase letters.
Step 2: Also under the branch, double-click “DefaultPassword” in the right window of the Registry Editor, and enter your password in the blank field. If you do not find the “DefaultPassword” item, you can create the string value by following the steps above.
Step 3: Next, double-click “AutoAdminLogon” in the right window to set the value to “1”. If you do not find “AutoAdminLogon”, you can follow the steps above to create a new one.
Now close the Registry Editor and restart your computer. Later you will find that the annoying login dialog is gone.
