I love this tip, useful for avoiding shutting down Live Messenger every time you finish a chat in Windows 7…
If you’re a heavy user of IM, you may love the way that Windows Live Messenger is front and central on the taskbar, where you can easily change status and quickly send an IM to someone
On the other hand, you may prefer to keep Windows Live Messenger in the system tray where it’s been for previous releases. If so, you can fool the application into the old style of behavior. To do this, close Windows Live Messenger, edit the shortcut properties and set the application to run in Windows Vista compatibility mode. Bingo!
