In Windows Live Messenger 2009 on Windows Vista and Windows 7, Aero is used for drawing the window frames of your contact list and conversation (chat) windows. You want the original Messenger frame back, but you don’t want to disable Aero completely in Windows?
The solution is: Use the Messenger Aero Switcher. Messenger Aero Switcher allows you to disable Aero effects for Messenger only. In order to use it, you should be on Windows Vista or Windows 7 with enabled Aero, and you should have the latest Windows Live Messenger 2009 QFE2 (14.0.8089.0726) installed.
