Maxifier is a freeware app for Windows 7 & Vista Media Center, which allows you to tweak its settings and lets you access its features easily from the notification area, in a multi-monitor environment.
Do note that if you do not have two monitors attached, most of Maxifier will not do anything. Normally when running Windows 7 or Vista Media Center maximized on a second screen, Media Center captures the mouse so you can not move it on to the main screen.
The Maxifier maximizes Media Center on the second screen, but allows you keep control of the mouse.
The app is implemented as a Tray Icon; which sits in the Notification Area of the taskbar.
Once it is started, access The Maxifier’s functions by clicking on the icon in the System Tray, with either the left or right mouse button.
