Virtual Screen Maximizer is one of those tiny programs created for one specific function. It is a free tool that needs no installation, designed for those users who work with various monitors at the same time, and which lets you maximize the windows with a simple keyboard shortcut. This shortcut can be configured from the "Config" option.
By working with Virtual Screen Maximizer it is really easy to maximize and restore windows. You just have to be careful choosing the keyboard shortcuts, so they don`t interfere with the normal use, for example, of a text editor.
