The First Windows Operating System - Windows 1.0
Windows 1.0 released in 1985 and used MS-DOS as its interface. With MS-DOS you could only issue commands at the command prompt (C:\). With Windows 1.0, it was changed from MS-DOS to graphics mode. A mouse could be used as a point and click device, but very few people had one. Without a mouse, it was harder to use than MS-DOS. It came pre-installed with applications such as the calendar, notepad, clock, and calculator. Tiled windows were used, but could only have one application open at a time. Other applications would have to be minimized. Even though this was new technology, it was not widely popular and hard to use. It was a very error prone operating system.
Windows 1.0 was available only on floppy disks, and you had to have MS-DOS on your computer before you could install it. It could be purchased for around $99.00.
Windows 2.0 - 1987
In Windows 2.0, you could tile windows to have one application open at a time without others having to be minimized. You started hearing the terms Minimize and Maximize instead of Iconize and Zoom.
Windows 3.0 - 1990
This was the first Windows version that had Desktop backgrounds and a Program Manager, File Manager and Print Manager. Quick launch icons were introduced. It had 16 colors and used the Intel 386 processor. Shortly after Windows 3.1 came out and this version had screensavers.
Windows NT 3.1 - 1993
NT stands for New Technology and this version of Windows used the 32-bit operating system. Earlier versions of Windows used 16-bit/32-bit operating system.
Windows 95 - 1995
This version of windows introduced open window buttons, the Start button, and a clock. The My Computer and Recycle Bin icons were added.
Windows NT 4.0 - 1996
Windows NT 4.0 was directed to the business market. It looked very similar to Windows 95. It was popular for its stability and users were able to close stalled applications without having to shut down the whole operating system.
Windows 98 - 1998
The first version of Windows 98 was not very popular and only lasted 12 months. The main thing people did not like is that the computer would shut down if left on for more than 50 days
