Sometimes Windows Live Messenger does not sign in and gives the option of trouble shooting, and sometimes that even does not work.

The first time when you sign-in into Windows Live Messenger, 2 folders are created in Windows Live Contacts folder, which occupies a couple of MB’s of hard drive. These are temporary files.

Windows Live Contacts folder is situated in…

(Windows Vista & 7)
C:\Users\YourUserName\AppData\Local\Microsoft\Windows Live Contacts\

(Windows XP)
C:\Documents and Settings \"user name"\Local Settings\Application Data\ Local\Microsoft\Windows Live Contacts\
OR
C:\Documents and Settings \"user name"\ Application Data\ Local\Microsoft\Windows Live Contacts\

*AppData is a hidden folder (View Hidden Files)

Before you enter Windows Live Contacts folder, make sure to sign-out of Windows Live Messenger (if you are signed-in) & exit Windows Live Messenger, even from the system tray (where time is displayed). Even unpin it from taskbar (for Windows 7).

Now once you are in the folder Windows Live Contacts, Delete all the folders that you can see (Shift + Del) (Delete permanently).

Now you’ll be able to sign-in into Windows Live Messenger.
