Introduction to Microsoft Windows
The oldest of all Microsoft’s operating systems is MS-DOS (Microsoft
Disk Operating System). MS-DOS is a text-based operating system. Users
have to type commands rather than use the more friendly graphical user
interfaces (GUI’s) available today. Despite its very basic appearance,
MS-DOS is a very powerful operating system. There are many advanced

underpins Windows. Many advanced administration tasks in Windows can

allowed for easier navigation of the system features. Windows 1.01
