Presently most of us work with multiple monitors and Windows 7 has some nice options for multiple monitor set up. Moving application windows between the monitors is a common task on multi-monitor systems and MonitorSwitch is a freeware tool which helps you to quickly move application windows between monitors. MonitorSwitch also adds custom menu commands to the window (or system) menu of applications that lets you quickly move windows between monitor.
You can enable or disable monitor switch from the options, the application sits in the Windows system tray.
MonitorSwitch works with all versions of Windows and is also 64bit compatible.
The same effect can be achieved by clicking on the top of any window with the middle mouse button.
