Microsoft windows operating systems

  1. 1. MicrosoftWindows Operating systems
  2. 2. Overview • Microsoft Corporation is anAmerican multinational corporation headquartered in Redmond, Washington, that develops, manufactures, licenses, supports and sells computer software, consumer electronics and personal computers and services. Its best known software products are the Microsoft Windows line of operating systems, Microsoft Office suite, and Internet Explorer web browser. • It is the world's largest software maker measured by revenues. It is also one of the world's most valuable companies. • Microsoft was founded by Bill Gates and Paul Allen on April 4, 1975
  3. 3. Windows 1.0 • Graphical personal computer operating environment. • 16-bit multi-tasking shell on top of an existing MS-DOS installation. • Graphical user interface software suite for IBM PC compatibles • Described as front-end of MS-DOS Operating system • Introduced device drivers for better graphics • Usage of mouse for navigation was encouraged November 20 1985
  4. 4. • Requires two floppy disk drives and • 256 KB of RAM • Offers limited multitasking of existing MS-DOS programs • Does not allow windows overlapping • Poor response from critics.
  5. 5. Windows 2.0 • Windows 2.0 is a 16-bit MicrosoftWindows GUI-based operating environment. • Allows windows overlapping. • Keyboard shortcuts were introduced. • Terminology of minimize , maximize and control panel were introduced. • Does not require hard disk. • VGA graphics introduced with 16 colors only. • The firstWindows versions of MicrosoftWord and Microsoft Excel ran on Windows 2.0. December 19 1987

  8. 8. Windows 2.1 • Windows 2.1 is one of the family of Microsoft Windows graphical user interface- based operating environments. • Windows/286 2.10 andWindows/386 2.10, less than a year after the release ofWindows 2.0.These versions can take advantage of the specific features of the Intel 80286 and Intel 80386 processors. • A hard disk was required for the first time to install Windows. May 27, 1988
  9. 9. Legal conflict with Apple • On March 17, 1988, Apple Inc. filed a lawsuit against Microsoft and Hewlett- Packard, accusing them of violating copyrights Apple held on the Macintosh System Software. Apple claimed the "look and feel" of the Macintosh operating system, taken as a whole, was protected by copyright and thatWindows 2.0 violated this copyright by having the same icons.The judge ruled in favor of Hewlett-Packard and Microsoft in all but ten of the 189 patents that Apple sued for. The exclusive ten could not be copyrighted, as ruled by the judge.
  10. 10. Windows 3.0 • Windows 3.0, a graphical environment, is the third major release of Microsoft Windows • Technical improvements were made to make better use of the memory management capabilities of Intel's 80286 and 80386 processors. • Requires 8086/8088 processor or better • Requires 384K of free conventional memory (real mode), 1MB (Standard Mode), or 2MB (Enhanced Mode) • Requires Hard disk with 6-7MB of free space May 22, 1990
  11. 11. Windows 3.0 was the only version ofWindows that could be run in three different memory modes: • Real mode, intended for older computers with a CPU below Intel 80286. • Standard mode, intended for computers with an 80286 processor. • 386 Enhanced mode, intended for newer computers with an Intel 80386 processor or above.
  12. 12. • It became the first widely successful version ofWindows and a rival to Apple Macintosh and the Commodore Amiga on the GUI front. • A "multimedia" version,Windows 3.0 with Multimedia Extensions, was released in 1991 to support sound cards as well as CD-ROM drives, which were then becoming increasingly available.

April 6, 1992
  14. 14. Disadvantage • Windows 3.1 uses a cooperative multitasking system, which means that your computer attempts to give equal memory to all programs at once.This means that the more programs you open, the more divided the memory. Enough programs open (more than 3) and the operating system has a tendency to crash.
  15. 15. Windows N.T 3.1 • 32-bit operating system • Microsoft had co-developed with IBM • Two problems regarding RISC architecture and Unix platform July 27,1993
  16. 16. • Three goals: 1. Portability 2. Reliability 3. Personality

  18. 18. Windows N.T 3.5 • Includes integrated Winsock andTCP/IP support. • Can share files through FTP and printers through LPR. It can act as a Gopher, Web orWAIS server. • Includes Remote Access Service for remote dial-up modem access to LAN services, and it includes the first implementation of Microsoft DNS. • Ability to use names of up to 255 characters for computer files. September 21, 1994
  19. 19. • Windows NT 3.5 has no drivers for PCMCIA adapter cards; thus it was unfit for use on laptops. • Refuses to install on a processor newer than the original Pentium.[16] Windows NT 3.51 fixed this. However, modifying files on the installation CD allows it to install.
  20. 20. Microsoft Bob • Microsoft Bob presented screens showing a "house", with "rooms" that the user could go to containing familiar objects corresponding to computer applications. March 1995
  21. 21. • Microsoft Bob was much criticized in the press, did not gain wide acceptance with consumers, and was not a successful or long-lived product.

  25. 25. • Much of the stability was gained by the use of protected memory. Direct hardware access was disallowed and "misbehaving" applications were terminated without needing the computer to be restarted • Numerous stability issues did occur as graphics and printer vendors had to change their drivers to be compatible. • Included a newWindowsTask Manager application • Poorly written drivers became a frequent source of "stop errors“ • less user-friendly thanWindows 95 when it comes to certain maintenance and management tasks. • The maximum amount of supported physical RAM inWindows NT 4.0 is 4 GB.
  26. 26. June 25,1998
  27. 27. • It is a hybrid 16-bit/32-bit monolithic product with an MS-DOS based boot stage. • Windows 98 includes Internet Explorer 4.01.

  31. 31. • Included the same games asWindows NT 4.0 did: FreeCell, Minesweeper, Pinball, and Solitaire. • The Recovery Console is usually used to recover unbootable systems. • The nature of attacks onWindows servers changed: more attacks came from remote sources via the Internet.This has led to an overwhelming number of malicious programs.

  41. 41. Oct 22, 2009
  42. 42. • Windows 7 was primarily intended to be an incremental upgrade to the operating system, intending to address criticisms faced by its predecessor, WindowsVista (such as performance improvements), whilst maintaining compatibility with hardware and software designed forVista. • A new "Action Center" interface was also added to provide an overview of system security and maintenance information. • New features are advances in touch and handwriting recognition, improved performance on multi-core processors, improved boot performance. • The first OS to have an ability to pin its apps onto its taskbar.
