Change Your Picture
You can find the User Accounts Applet by clicking Start | Control Panel | User Accounts. In the User Accounts applet, you can change your picture. Ya know, something tells me that a toy frog, rubber duckie, and soccer ball don't represent your personality as much as something else does. Click "Change my picture" then "Browse for more pictures." Windows will be smart enough to resize whatever you pick. Awww, isn't that nice?
