2. Change Names on computer:
For Windows XP users:

Under "Computer name:", enter a different computer name that is no longer than 8 characters. Click "OK." It will prompt you to restart your computer, TAKE CARE TO NOT RESTART YOUR COMPUTER OR YOU WILL HAVE TO RESTART THE PROCESS!
b. Now, go back to Start>Control Panel>User Accounts>Change an Account>Computer Administrator (with name of your account)>Change my name. Change the name to a new name. Click "Change Name." AGAIN, DO NOT RESTART YOUR COMPUTER AT THIS POINT!
