Windows Live Messenger

What is Windows Live Messenger?

Windows Live Messenger is an instant messaging client connects to Microsoft Messenger service. Microsoft announced that Windows Live Messenger will be retired in favor of Skype. Windows Live Messenger's album viewer is based on Windows Photo Gallery and provides users a photo viewing experience for photo albums shared via SkyDrive and Facebook.


The most used version is 8.1.0178.00, with over 98% of all installations currently using this version. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The main program executable is MsblIco.Exe. The software installer includes 135 files and is usually about 785.5 KB (804,352 bytes).
