Windows 1.0 : Front-End to The MS_DOS OS turn 30

Microsoft Windows 1.0 is a graphical personal computer operating environment, developed by Microsoft Corporation. Windows 1.0 was released on November 20, 1985 as the born of the Microsoft Windows line. Bill Gates the richest man on the Earth is the founder of the Microsoft had worked with founder of a multinational company Apple Steve Jobs to develop application for Apple’s January 1984 original Macintosh (the first mass produced personal computer with a graphical user interface).

The initially announced version of windows had features so much resembling the Macintosh interface that Microsoft had to change many of them: overlapping windows, although supported by GUI engine, weren’t allowed for exactly this reason.

Windows 1.0 is a 16-bit multi-tasking graphical personal computer operating system. Windows 1.0 was Microsoft’s attempt at a graphical multitasking operating system for the IBM PC. Microsoft 1.0 is an MS_DOSC program. But the main thing is that Windows 1.0 can able to call MS_DOS functions, and also GUI programs are run from .exe file just like MS_DOS.

The system requirements for Windows 1.01 constituted CGA/HGC/EGA (listed as “Monochrome or color monitor”), MS-DOS 2.0, 256 KB of memory or greater, and two double-sided disk drives or a hard drive. Beginning with version 1.03, support for Tandy and AT&T graphics modes was added.

Windows 1.0 does not allow overlapping the windows, instead all windows are tiled. Only and only a dialog box appear over the windows. The great thing about the Windows 1.0 is that it require only 320 KB RAM or greater and only 720 KB disk space. Which is negligible in current version.

Now, rather than typing MS‑DOS commands, you just move a mouse to point and click your way through screens, or “windows.” Bill Gates says, “It is unique software designed for the serious PC user.”


Windows 1.0 requires a minimum of 256 kilobytes (KB), two double-sided floppy disk drives, and a graphics adapter card. A hard disk and 512 KB memory is recommended for running multiple programs or when using DOS 3.0 or higher.

There are drop-down menus, scroll bars, icons and dialog boxes that make programs easier to learn and use. With windows 1.0 we are able to switch among several programs without having to quit and restart each one. Windows 1.0 ships with several programs, including MS‑DOS file management, Paint, Windows Writer, Notepad, Clipboard Viewer, Reversi, Calculator, Terminal, Calendar, cardfile, Clock and many other to help you manage day-to-day activities.

It was Microsoft’s first attempt to implement a multitasking graphical user interface-based operating environment on the PC platform. Microsoft ended support for Windows 1.0 on December 31, 2001.

Now, after about 30 years Microsoft created history by developing different operating system. And Windows 10 is just doing great things. Within 2 and half month of releasing Windows 10 more than 110 million devices running with the Windows 10. Now the next aim of the Windows is to release Windows 10 for the Lumia devices. According to shareholders Microsoft have to release the Windows 10 for Lumia as a tribute of Windows 1.0. Microsoft Windows came to dominate the world’s personal computer market with over 90% market share, overtaking Mac OS, which had been founded introduced in 1984. Windows 1.0 is often regarded as a “front-end to the MS_DOS operating system”, a description which has also been applied to subsequent versions of Windows.
