If you’re not familiar with Windows Live Messenger, we recommend you check out our new Windows Live Messenger guide, where we explain all the new features included in this FINAL version, including:

  • Shared Folders : Using shared folders, you can synchronize folders with your friends and share everything they contain. They will automatically update whenever a change is made to that shared directory, such as adding or removing a file.
  • Make low-cost calls : You can also make much cheaper calls to landlines and mobile phones using VoIP technology.
  • Offline messages : You can receive messages left by your contacts when you weren’t online and read them as soon as you log in.
  • Chat while offline : You can now chat with a contact even if they are offline because you don’t want to be disturbed.
  • Windows Live Contacts : A contact book for all Windows Live services like Messenger, Mail, or Spaces that will automatically update whenever one of your contacts changes their personal information like their email address or phone number.

This download is the latest version available in Spanish. More information is available on the official Windows Live Messenger website.

Please note that with this new version, many Messenger programs may stop working properly. Please wait patiently for the developers to release new versions compatible with this new messenger.
