Setting Up User Accounts and Passwords on a Windows 7 Home Network
Enter a new password for the user account and confirm the new password; then click Create Password.
You should also create a password hint to help you remember the password in case you forget it.
The password hint will be visible to everyone. Although the hint should be helpful in remembering the password, it should not be a dead giveaway (for example, Mom’s maiden name or Make and model of my car). Try something more subtle.
