How do you change your user name and password on your computer when you log in?

Assuming you are using Windows XP, click on the Start button, then click on Control Panel. Select User Accounts Click on Change An Account Click on the account you are now using You will then have the option of changing your log on name, or password, etc. BE CAREFUL on changing passwords. If you make a mistake or can't remember the new password, there is no way of obtaining the password you entered. You would then have to re-install windows with the resulting loss of all data on the hard drive when you do the re-install. WRITE DOWN THE NEW PASSWORD AND DOUBLE CHECK IT BEFORE MAKING THE CHANGE.
