Important Dates in Microsoft’s History

Apri 4, 1975: Microsoft is founded by Paul Allen and Bill Gates with the purpose of developing and selling BASIC interpreters for Altair 8800, a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. The company’s name spelled as Micro-Soft at the time.

January 1, 1979: Microsoft moves its headquarters from Albuquerque, New Mexico to Bellevue, Washington.

June 25, 1981: Incorporation of Microsoft.

August 12, 1981: IBM introduces its first personal computer which runs MS-DOS 1.0, Microsoft’s 16-bit operating system.

November 20, 1985: Microsoft releases Windows 1.0, a graphical personal computer operating environment that enabled users to see user friendly icons on screen. The release of the Windows 1.0 meant the end for Microsoft’s command-line DOS (short for Disk Operating System), but the first version of Windows could only support tiled windows. It had, though, desktop features such as the MS-DOS Executive file manager, Notepad, Calendar, Terminal, Cardfile, Clock, Calculator, Clipboard, Print Spooler, and RAMDrive for managing memory cards designed to beat the PC’s 640KB memory limit, Windows Paint and Windows Write, Windows 1.0 even had a game, called Reversi.Windows 1.0 cost $99, as a special introductory offer.

February 26, 1986: Microsoft Inc. moves to corporate campus in Redmond, Washington.

March 13, 1986: Microsoft becomes a public stock company.

December 9, 1987: Windows 2.0 is released. It is a 16-bit GUI-based operating environment, the successor to Windows 1.0.. Windows 2.0 allowed application windows to overlap each other unlike its predecessor Windows 1.0, which could display only tiled windows. Windows 2.0 was also the first Microsoft’s platform which could run Microsoft’s Word and Excel applications. Windows 2.0 used the real-mode memory model, limiting memory access to 1MB.

August 1, 1989: Microsoft introduces the first version of Office suite of productivity applications.

May 22, 1990: Microsoft launches its Windows 3.0 graphical environment, the first widely successful version of Windows. This version saw significant interface changes (everything now looked much better thanks to this version’s support for 256-color VGA), as well as improved exploitation of the Intel 286 and 386 processors’ memory management capabilities. This version introduced Program Manager and File Manager, along with a redesigned Control Panel and Solitaire game which remains a Windows staple to our days.

July 27, 1993: Windows NT is launched. Born from the wreckage of Microsoft’s ill-fated partnership with IBM, Windows NT was built from the ground up under the leadership of ex-DEC software engineer Dave Cutler. The platform was initially developed for the Intel i860, and its N-Ten codename fave the version its name (but Microsoft said later that NT meant New Technology).  Windows NT 3.1 will be a fully 32-bit pre-emptive “multitasking, multithreaded, multiprocessing, multiuser operating system”. It was equipped with a hybrid kernel and a hardware abstraction layer to facilitate porting between processor platforms. Various NT variants have appeared on many CPU architectures through the years, including IA-32, x86-64, MIPS, Alpha, PowerPC, ARM and Itanium.

August 24, 1995: Microsoft launches Windows 95, is a consumer-oriented operating system, which was a significant improvement over the company’s previous DOS-based Windows products. This platform entered the market with unprecedented push. Microsoft used the Rolling Stones song Start Me Up to introduce its new platform. This operating system was a consumer-oriented hybrid 32-bit/16-bit OS with a brand-new user interface. Many new features were built in, such as plug-and-play automatic device detection and configuration. Its user interface saw the first appearance of the long-running Windows features such as the Start button and menu. The platform had the taskbar and system tray or notification area, as well as maximize, minimize and close buttons on windows.

December 7, 1995: Bill Gates outlines Microsoft’s commitment to supporting and enhancing the Internet.

April 1997: Microsoft introduced USB support. This new feature is released with Windows 95 OSR2.1.

24 August 1996: Available in Workstation and Server versions at the moment of its release, Windows NT 4.0 is introduced to the public. The 4.0 will be followed by Server, Enterprise Edition in 1997 and Terminal Server in 1998. Windows NT 4.0 added the Windows 95 user interface to the fully 32-bit, business-oriented operating system. NT 4.0 included a number of architectural improvements. In particular, the Graphics Device Interface, or GDI, was moved into kernel mode, giving a significant performance boost over NT 3.5x, although this also required graphics and printer drivers to be updated. NT 4.0 was the first Windows version to support the DirectX multimedia API.

August 6, 1997: At the MacWorld Boston event in August 1997, Steve Jobs, in a ground-breaking decision, Jobs announces an alliance with Microsoft. In exchange for $150 million in Apple Stock, Microsoft and Apple would have a 5-year patent cross-license and, more importantly, a final settlement in the ongoing GUI argument. Microsoft agrees to pay an unreleased sum of additional funds to quiet the allegations that it had stolen Apple’s intellectual property in designing its Windows OS. Microsoft also announces that Office ’98, its popular office package, would be available for the Mac by years end.

May 15, 1998: Microsoft launches Windows 98, a graphical operating system, the second major release in the Windows 9x line of operating systems and the successor to Windows 95. The company released the system to retail on June 25, 1998. One of the best known and famous versions, its popularity was due mostly to more consumer-friendly interface than its predecessors. Besides, a range of user-interface enhancements were introduced via the bundled Internet Explorer 4’s Windows Desktop Update. The improvements included the Quick Launch toolbar, Active Desktop, the ability to minimize a window by clicking its toolbar icon, plus backward and forward buttons, and an address bar, in Windows Explorer. USB support (first introduced with Windows 95 OSR2.1 in April 1997), was also improved in Windows 98. It encompassed keyboards, mice, joysticks, hubs, scanners (but not modems, printers or storage devices). Windows 98 SE followed suit.

January 13, 2000: Steve Ballmer is named president and chief executive officer for Microsoft.

February 17, 2000: Microsoft launches Windows 2000 Professional. This version was built on the Windows NT 4.0 code base and replaced both NT 4.0 and Windows 98. Windows 2000 Professional brought important improvements such as plug and play with full ACPI and WDM support. It also offered many features designed for the Windows 98 and Windows 98 SE product line. Windows 2000 edition also introduced NTFS 3.0, the Encrypting File System (EFS), Logical Disk Manager, an LDAP/Active Directory. Besides Windows File Protection prevented unauthorised programs from modifying critical system files.

June 22, 2000: Bill Gates and Steve Ballmer outline Microsoft’s .NET strategy for Web services.

September 14 2000: The customer-focused Windows ME (short for Millennium Edition) is released. This was the last of the DOS-based Windows 9x line. However, the Millennium Edition is widely regarded as one of the worst Windows versions Microsoft ever released, because this hurriedly released version was notorious for being buggy and crash-prone. Minimum system specifications for Windows ME were a 150MHz Pentium processor with 300MHz recommended, 32MB of RAM (64MB recommended), and 320MB of hard disk space (2GB recommended). The system could address up to 1.5GB of RAM. Unlike Windows 95 and 98, Windows ME lacked real-mode DOS support. It included, however, the System Restore feature, which allowed users to take the system back to a previous stable configuration. Windows ME was quickly superseded by the far superior NT-based Windows XP.

May 31, 2001: Microsoft launches Office XP.

October 25, 2001: Microsoft launches Windows XP. It initially comes in Professional and Home versions. This version, equipped with a couple of Service Packs under its belt, XP – for eXPerience – proved to be one of Microsoft’s most successful Windows releases ever. It extended support for this durable OS ended on April 8, 2014. That’s it lasted for an unprecedented twelve and a half years after its launch. The XP user interface was very friendly. Indeed, it featured an updated two-column Start menu, task-grouping support on the taskbar and the ability to lock the taskbar, among other enhancements. Microsoft presented all the improvements in a new default Luna visual style.

January 30, 2007: Microsoft launches Windows Vista and the 2007 Microsoft Office System to consumers worldwide. This controversial system had a convoluted gestation, a delayed birth, and a relatively short life. Many remember Windows Vista as a particularly ill-conceived Windows release. The main complaints centered on security features, digital rights management, hardware requirements, hardware performance and software compatibility. Longhorn (Vista’s codename) was built on Windows Server 2003 SP1, having jettisoned key features such as WinFS. Features included the Aero interface, which with the right hardware displayed transparent windows and other visual effects, and a redesigned Start menu.

February 27, 2008: Microsoft launches Windows Server 2008, SQL Server 2008 and Visual Studio 2008.  This platform was built on the same code base as Windows Vista. Windows Server 2008 included new features like Network Access Protection (NAP) which checks that PC connects to the network are complying with IT policies; Server Core, which installs a minimalist Graphical User Interface and a limited set of server roles, PowerShell and Read-Only Domain Controllers. Existing components such as IIS, Terminal Services and the SMB file-sharing protocol also received thorough overhauls.
