| Microsoft Windows is the most popular operating system for personal computers. There are several versions of the Windows operating system, including Windows XP (for home users) and Windows 2000 (for professional users). Earlier versions of Windows include Windows 3.1, 95, 98, ME, and NT. All Windows platforms use a graphical user interface (GUI), like the Mac OS, and also offer a command-line interface for typing text commands. |
