Windows Live Messenger (aka MSN Messenger) kept popping up with an annoying notification saying "You have 1 invitation". Stupid spam bots sending crap to accounts that I never use...
But even though I clear the damn thing, it keeps coming back.
To fix this, close Windows Live Messenger. First open up Windows Explorer and paste in the following path.
(Windows Vista and Windows 7)
%USERPROFILE%\AppData\Local\Microsoft\Windows Live Contacts
(Windows XP)
%USERPROFILE%\Local Settings\Application Data\Microsoft\Windows Live Contacts
Now delete all the files in that folder. You can back it up first if you really wanted to.
Whalla, that is all. The problem should now be fixed.
