Did your computer fail to open a WINDOWSLIVECONTACT file? We explain what they are used for and recommend software that we know can open or otherwise handle your .WINDOWSLIVECONTACT files.


Files that contain the .windowslivecontact file extension store the contact files for the Microsoft Live Messenger program. Microsoft Live Messenger is an instant messaging application that allows users to IM (instant message) or "chat" over the Internet in real time.

The WINDOWSLIVECONTACT file stores a list of contacts that the user saves within the Microsoft Live Messenger application. These contacts are commonly individuals that the user "chats" with on a regular basis using the Microsoft Live Messenger application. When a user adds a new contact to his or her contacts list or removes a contact from the list, the WINDOWSLIVECONTACT file is then updated.
