My laptop runs on Windows 7 and my email exchange software is Windows Live Mail Version 2009 (Build 14.0.8089.0726). Four email accounts are registered with Windows Live Mail and everything is running smoothly, no problem. I want to have the ability to log into Windows Live Mail with a master password each time I log into Windows; i.e. each time I click on the software icon on Windows tray Windows Live Mail should ask me a password to log me in. Is there such a characteristic within Windows Live Mail?
