The Evolution of Windows

"Windows is a flop!" When version 1.01 made it's appearance at the end of 1985, no one wanted it. Apple threatened to take legal action for using Macintosh features like the menu bar, program windows, drop down menus and mouse support.
At that time Apple was IT giant while Microsoft a small fish. However, after IBM machines started dominating the markets so did Microsoft's Operating System DOS. It tasted success with version 2.0. Microsoft later switched from 16 bits OS and DOS platform to more stable 32 bits and NT kernel. Windows 95 introduced the concept of task bar and start menu.
