Microsoft will shut down Windows Live Messenger next year, compelling users to migrate to Skype, whose latest version can import users' Messenger contacts.

By updating to the latest Skype, Messenger users can instant message and video call their Messenger friends. Messenger users just need to update to the latest version of Skype, sign in using a Microsoft account, and their Messenger contacts will be there.

"We want to focus our efforts on making things simpler for our users while continuously improving the overall experience," Skype said.

Skype will retire Messenger in all countries worldwide in the first quarter of 2013 (with the exception of mainland China where Messenger will continue to be available).

Some of the other features Messenger users can expect:

- Broader device support for all platforms, including iPad and Android tablets
- Instant messaging, video calling, and calling landlines and mobiles all in one place
- Sharing screens
- Video calling on mobile phones
- Video calling with Facebook friends
- Group video calling

Microsoft acquired Skype in October 2011 for US$8.5 billion.
