You can uninstall Windows Live Messenger.
From your start menu, click Control Panel.
From Control Panel, choose Programs and Features.
When the Uninstall panel opens, scroll down and look for Windows Live Essentials and click it.
You will then be given a choice to remove or repair, choose Remove.
A list of installed Windows Essentials applications will be presented. Check the box for Messenger, then click Uninstall. If there are any other Live Essential programs you want to uninstall, check those boxes also.
Not long ago, I received an update for Windows Live Essentials 2011, so it is possible that you did also and that's how it ended up on your computer. If this is the case, you may end up getting it reinstalled if you have Microsoft updates set to automatically install.
