Windows Live Messenger 15.4.3538.0513

Windows Live Essentials (previously Windows Live Installer) is a suite of freeware applications by Microsoft which aims to offer integrated and bundled e-mail, instant messaging, photo-sharing, blog publishing, security services and other Windows Live entities. Essentials programs are designed to integrate well with each other, with the Windows operating system, and with other Windows Live web-based services such as Windows Live Photos and Windows Live Hotmail, so that they operate as a “seamless whole”. Windows Live Essentials will be integrated with Windows 7 (but not "bundled" with Windows 7) and available to be downloaded from Windows Live Downloads.

Windows Live Family Safety
