How to Make Windows Remember My Login & Password
Having a specific login account and password is a good security measure for any computer, preventing unauthorized users from gaining access to your system. Asking Windows to remember your login and password streamlines the process, but it should be done only when you are certain that you are the only person with access to your particular computer. Otherwise, anyone can log in to your computer without even having to guess your login ID or password.
Click "Start" and type "Run" in the "Search" box. Press "Enter."
Type "control userpasswords2" and press "Enter."
Uncheck "Users must enter a username and password to login." This forces Windows to remember your login information, preventing you from needing to input it.
