UPDATE (4/23/2013): Use Messenger Reviver 2 instead to bypass the forced upgrade to Skype.
Microsoft today started forcing upgrades to Windows Live Messenger 2011 on Windows 7. Unfortunately the 2011 version drops several key features, adds several annoying features, and is not that impressive of an upgrade. Certainly many just prefer to use Live Messenger 2009 and now you can (again).
