( Co – Founded with Paul Allen) He is consistently ranked among the worlds wealthiest people and was the wealthiest overall from 1995 to 2009. During his career at Microsoft, Gates held the positions of CEO and chief software architect, and remains the largest individual shareholder. He has also authored and co-authored several books. http://en.wikipedia.org/wiki/Bill_Gates
  • 4.  Harvard University (Dropped out) US$ 66 billion (2012) In Indian Rupees 3572580000000.00 ₹
  • 5.  Microsoft Corporation is an American multinational software corporation headquartered in Redmond, Washington. That develops, manufactures, licenses, and supports a wide range of products and services related to computing. The company was founded on April 4, 1975. Microsoft is the worlds largest software maker measured by revenues. It is also one of the worlds most valuable companies. Total Assets US$ 121.2 billion (2012) 6560556000000.00 ₹ In 1975, Gates and Allen form a partnership called Microsoft. Like most start-ups, Microsoft begins small, but has a huge vision- “A computer on every desktop and in every home.” http://en.wikipedia.org/wiki/Microsoft
  • 6. MS-DOS In June 1980, Gates and Allen hire Gates’ former Harvard classmate Steve Ballmer to help run the company. The next month, IBM approaches Microsoft about a project code-named "Chess." In response, Microsoft focuses on a new operating system—the software that manages, or runs, the computer hardware and also serves to bridge the gap between the computer hardware and programs, such as a word processor. It’s the foundation on which computer programs can run. They name their new operating system "MS-DOS." When the IBM PC running MS-DOS ships in 1981, it introduces a whole new language to the general public. Typing “C:” and various cryptic commands gradually becomes part of daily work. MS-DOS is effective, but also proves difficult to understand for many people. There has to be a better way to build an operating system. Geek trivia: MS-DOS stands for Microsoft Disk Operating System.
  • 7. 1982–1985: Introducing Windows 1.0  On November 20, 1985, two years after the initial announcement, Microsoft ships Windows 1.0.  Now, rather than typing MS-DOS commands, you just move a mouse to point and click your way through screens, or “windows.” There are drop-down menus, scroll bars, icons, and dialog boxes that make programs easier to learn and use. Youre 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, Calculator, and a calendar, and clock to help you manage day-to-day activities. There’s even a game—Reversi.Geek trivia: Remember floppy disks and kilobytes? Windows 1.0 requires a minimumof 256 kilobytes (KB), two double-sided floppy disk drives, and a graphics adaptercard. A hard disk and 512 KB memory is recommended for running multiple programsor when using DOS 3.0 or higher.
  • 8. When Windows 1.x starts, it launches the MS-DOS Executive. The MS-DOS executive is kind oflike File Manager or Explorer, except there are no icons and no drag-and-drop. Programs anddirectories can be opened by double-clicking, but other disk functions must be done through themenu.
  • 9. In Windows 1.x you are stuck with tiled windows. The control in the upper right corner of eachwindow is a "resize" control. Dragging it around will move the top edge of the window anddouble-clicking will "zoom" the window to full screen. Some programs have a "resize" control inthe lower right corner of the window as well.
  • 10. The control in the upper left of the window is the system box. Clicking once on this box bringsup a menu of available window options for the current window. In this version of Windows, italso contains the applications "About" information.
  • 11. This screen shot shows the Windows 1.01 version of Notepad. It has a very small fixed sized textbuffer, 16k or so, and therefore can only open small text files.
  • 12. This version of Notepad even shows how much space is free in its text buffer.
  • 13. This screen shot shows Notepad in a "zoomed" state, taking up the full screen.
  • 14. Here, The Windows 1.x calculator and the Windows clipboard demonstrates the abilityof Windows to share data between applications.
  • 15. Now the data is being pasted in to Microsoft Paint.This version of Paint is only capable of monochrome graphics and saves files in an .MSPformat.
  • 16. This is the screen color section of the Windows control panel. The gradient selection barssuggests possible support for true color graphics. Note that there is no way to easily selectsolid colors from any existing pallet
  • 17. A typical Windows dialog box showing option buttons, check boxes, a text box andcommand buttons. These controls are provided by Windows, so the program does notneed to worry about drawing or controlling them.
  • 18. The windows can be moved around the screen and can be tiled in different ways other thanhorizontally. This picture shows reversi and the clock tiled in the corner of the screen,although the edges of all of the windows are still locked together.
  • 19. Windows 1.01 can run some dos applications in a window. Surprisingly this version of windowscan start windows applications from the command prompt. When running multiple DOSapplications the applications appear to be multitasked.
  • 20. The best part of Windows 1.x.
  • 21. 1987–1992: Windows 2.0–2.11—More windows, more speed On December 9, 1987 Microsoft releases Windows 2.0 with desktop icons and expanded memory. With improved graphics support, you can now overlap windows, control the screen layout, and use keyboard shortcuts to speed up your work. Some software developers write their first Windows–based programs for this release. In 1988, Microsoft becomes the world’s largest PC software company based on sales. Computers are starting to become a part of daily life for some office workers. Geek trivia: Control Panel makes its first appearance in Windows 2.0.
  • 22. Like Windows 1.x, Windows 2.x starts up with the Windows MS-DOS Executive. Windowsversion 2.03 runs only in real mode like 1.x, however Windows 2.1 introduced 386 enhancedmode, which allowed Windows to use memory beyond 640k.
  • 23. Windows 2.x is packaged with the same applications as Windows 1.x, but the windowmanagement is significantly improved. Overlapping windows are allowed, and windowsmay be freely resized and moved on the screen. The window controls now consist of asystem box in the upper left, and a minimze and maximize or restore button in the upperright if they are applicable to the particular window.
  • 24. A dialog box, showing that controls have not changed much from 1.x.
  • 25. Minimized icons can be freely moved anywhere on the desktop. The area in the lowerright corner of windows with scroll bars that join is now a real "resize" control. Thecorners of any regular window can also be used to resize to window
  • 26. The best part of Windows 2.x :)
  • 27. 1990–1994: Windows 3.0–Windows NT—Getting the graphics On May 22, 1990, Microsoft announces Windows 3.0, followed shortly by Windows 3.1 in 1992. Taken together, they sell 10 million copies in their first 2 years, making this the most widely used Windows operating system yet. The scale of this success causes Microsoft to revise earlier plans. Virtual Memory improves visual graphics. In 1990 Windows starts to look like the versions to come. Windows now has significantly better performance, advanced graphics with 16 colors, and improved icons. Program Manager, File Manager, and Print Manager arrive in Windows 3.0.
  • 28.  Windows software is installed with floppy discs bought in large boxes with heavy instruction manuals. The popularity of Windows 3.0 grows with the release of a new Windows software development kit (SDK), which helps software developers focus more on writing programs and less on writing device drivers. Windows is increasingly used at work and home and now includes games like Solitaire, Hearts, and Minesweeper. For the first time, PCs become an integral part of the emerging client/server computing evolution.
  • 29. About this time Microsoft finally realized that the GUI was catching on. Functionally, the windowmanagement is not much different than version 2.x, however they took some steps to make itlook fancier. Command buttons and the window controls now have a 3D look. However this3Dnes did not extend to many other window controls.Microsoft replaced the old MS-DOS Executive with Program Manager and its companion, FileManager. Program manager gives the user large Macintosh like icons to click on to startprograms. Although program groups can not be imbedded in other program groups, the iconsare drag and dropable between groups.
  • 30. This is File Manager. Files can be managed relatively easily with the ability to drag anddrop between folders and drives.
  • 31. Windows 3.0 also includes a completely revamped control panel. Like Program Manager, thecontrol panel now displays using large icons.
  • 32. The Windows 3.0 control panel also allows you to change the background to display a specifiedpattern or bit-mapped graphic. Also, double-clicking on the desktop starts the Taskman program.Taskman is a small program that can be used for switching tasks more easily if many windowsare open, rearranging the open windows, and rearranging minimized program icons.
  • 33. Windows 3.0 also includes a new, very advanced hypertext help system. Yes, it looks like a webbrowser. The Windows 3.x help files worked quite well, unfortunately Microsoft ditched thisformat in Windows 95, probably so they could re-introduce this very same style of help withHyper Help in Windows 98.
  • 34. Another new application that was included with Windows 3.0 is Windows Paintbrush, areplacement for the old Microsoft Paint program in 1.x and 2.x. This program actuallyhandles color and supports .BMP and .PCX graphics formats.
