Having never used Messenger until recently. I find that I have a small irritating problem. My son and his friends have all logged onto their Messenger logins through our computer. Now I am using Messenger myself. My login details are about 6th on the list. It will not load the first time because it asks for my sons password. How do I delete all the other login details so that just mine remains?
-Control Panel --User Accounts ---Change User Account (select yours) ---Under 'related tasks' on left of window chose 'manage my network passwords' ---See list of 'stored usernames and passwords' (the list that appears when you try to log on)and delete those you no longer want.
Did this myself a while ago and it does the trick. Good luck.
