What VirtuaWin is

VirtuaWin is a free virtual desktop manager for Windows that organizes applications across separate desktops. Its home page describes support for up to nine desktops, while its FAQ states a limit of 20 desktops and a maximum of 160 managed windows. It has no graphical interface of its own; users control it with the keyboard or through a system tray icon. Application rules and virtual desktop controls are listed features. VirtuaWin is described as configurable and extensible, with optional modules that add functions without expanding the core application. The site provides a Module SDK with C example code and says modules can be developed in languages that support Windows executables. Downloads include VirtuaWin 4.5 installers, Unicode and portable builds, and C source code; the portable version can be unzipped and run anywhere. The program is distributed under the GNU General Public License. Some applications that use a special type of window may remain visible when desktops change, and the FAQ points to Window Rules for configuring them. Support information points users to the FAQ and official forum.
