An anonymous reader writes "Microsoft released the beta of the new 'Wave 4' Windows Live Essentials last week. The new beta of Windows Live Messenger 2011, while plugging some privacy holes and shoring up the user interface, fails to tackle the one biggest privacy-buster of all. Say you use Messenger to IM your wife. You also use Messenger to IM your old girlfriend. The next time your wife logs on to her Hotmail account — not Messenger, Hotmail — she will see that you and your old girlfriend 'are now friends.' It all happens without your knowledge or permission, and it happens even if you tell Messenger you want your personal information to be 'Private.'"
