What does it mean to remove a Yahoo! account?
After you add your Yahoo! account to your Media Center PC, you do not need to enter your user name and password to use the various Yahoo! applications on Media Center PC. This means that anyone using your Media Center PC can see your personalized Sports settings without a password. If you no longer want Yahoo! settings available on Media Center PC, then you can remove one or all of the added Yahoo! accounts from your Media Center PC. By removing a Yahoo! account that you added, you are only removing access to your Yahoo! preferences for Yahoo! Sports for TV.
