Windows 7 allows you to choose a picture to associate with your account. This is the image you click to log on to the computer. To change it, open Control Panel and choose Users Accounts. Under Users, click Change your Account Picture. You can select from a number of built-in images, or you can browse to one of your own images.

A password-reset disk is useful if you forget your password, but the catch is that you have to create it while you are logged in--if you have already forgotten your password, it's too late. You probably don't have a floppy drive on your PC, but a USB drive will work just fine. To create a password-reset disk, open Control Panel and select User Accounts and Family Safety, User Accounts. Click on Create a password reset disk in the left pane. A wizard will guide you through the procedure, asking you on which drive to place the password key as well as what your current password is. Be careful where you store the disk or USB drive--anyone who can access it can use it to gain entry to your account.
