What Does Virtual Desktop Manager Mean?
A virtual desktop manager (VDM) is software that facilitates customized user desktop designs for specific projects, applications or work environments. VDM users may alternate window groups with a mouse click or keyboard hot key. Each window is a unique and virtual user application desktop.

Desktop space is limited with tablets, ultra-mobile PCs (UMPC), BlackBerrys and smartphones. A VDM facilitates the movement of icons, folders and shortcuts between virtual desktops. One desktop selection or a consolidated matrix may be viewed, depending on user preference.
OS features allow application switching in Microsoft Windows (XP and later). For example, in some versions of Windows, the Alt-Tab function facilitates switching between open applications. Available windows display as icons on the bottom of the device screen, but the VDM remains unchanged.
