If you prefer messenger to appear in the notification area like it did in the past there is a trick. You have to fool the application into using its old behavior. To make this happen, follow the step below:
- Close Windows Live Messenger
- Right-click the Messenger shortcut, and select Properties for the icon in the Start menu.
- Click on the Compatibility tab, and set the application to run in Windows Vista compatibility mode. (See the graphic below)
- Press the OK button when done.
