microsoft history
Main articles: History of Microsoft and History of Microsoft Windows
Paul Allen and Bill Gates (respectively) on October 19, 1981 in a sea of PCs after signing a pivotal contract. IBM called Microsoft in July 1980 inquiring about programming languages for its upcoming PC line;[1] after failed negotiations with another company, IBM gave Microsoft a contract to develop the OS for the new line of PCs.[2]
Microsoft entered the OS business in 1980 with its own version of Unix, called Xenix.[6] However, it was DOS (Disk Operating System) that solidified the company's dominance. After negotiations with Digital Research failed, IBM awarded a contract to Microsoft to provide a version of the CP/M OS, which was set to be used in the upcoming IBM Personal Computer (IBM PC). For this deal, Microsoft purchased a CP/M clone called 86-DOS from Seattle Computer Products, branding it as MS-DOS, which IBM rebranded to PC-DOS. Following the release of the IBM PC in August 1981, Microsoft retained ownership of MS-DOS. Since IBM copyrighted the IBM PC BIOS, other companies had to reverse engineer it in order for non-IBM hardware to run as IBM PC compatibles, but no such restriction applied to the operating systems. Due to various factors, such as MS-DOS's available software selection, Microsoft eventually became the leading PC OS vendor.[2][7] The company expanded into new markets with the release of the Microsoft Mouse in 1983, as well as a publishing division named Microsoft Press.[8] Paul Allen resigned from Microsoft in February after developing Hodgkin's disease.[9]
1985–1994: Windows and Office

Microsoft introduced its office suite, Microsoft Office, in 1990. The software bundled separate office productivity applications, such as Microsoft Word and Microsoft Excel.[17] On May 22 Microsoft launched Windows 3.0 with a streamlined user interface graphics and improved protected mode capability for the Intel 386 processor.[18] Both Office and Windows became dominant in their respective areas.[19][20] Novell, a Word competitor from 1984–1986, filed a lawsuit years later claiming that Microsoft left part of its APIs undocumented in order to gain a competitive advantage.[21]
1995–2005: Internet and the 32-bit era
Bill Gates giving his deposition in 1998 for the United States v. Microsoft trial. Once the U.S. Department of Justice 1993 took over from the Federal Trade Commission, a protracted legal wrangling between Microsoft and the department ensued, resulting in various settlements and possible blocked mergers. Microsoft would point to companies such as AOL-Time Warner in its defense.[14]
Bill Gates handed over the CEO position on January 13, 2000 to Steve Ballmer, an old college friend of Gates and employee of the company since 1980, creating a new position for himself as Chief Software Architect.[4][29] Various companies including Microsoft formed the Trusted Computing Platform Alliance in October 1999 to, among other things, increase security and protect intellectual property through identifying changes in hardware and software. Critics decry the alliance as a way enforce indiscriminate restrictions over how consumers use software, and over how computers behave, a form of digital rights management; for example the scenario where a computer is not only secured for its owner, but also secured against its owner as well.[30][31] On April 3, 2000, a judgment was handed down in the case of United States v. Microsoft,[32] calling the company an "abusive monopoly";[33] it settled with the U.S. Department of Justice in 2004.[12] On October 25, 2001 Microsoft released Windows XP, unifying the mainstream and NT lines under the NT codebase.[34] The company released the Xbox later that year, entering the game console market dominated by Sony and Nintendo.[35] In March 2004 the European Union brought antitrust legal action against the company, citing it abused its dominance with the Windows OS, resulting in a judgment of €497 million ($613 million) and to produce new versions of Windows XP without Windows Media Player, Windows XP Home Edition N and Windows XP
windows 7
Windows 7 is the latest release of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs, and media center PCs.[4] Windows 7 was released to manufacturing on July 22, 2009,[5] and reached general retail availability on October 22, 2009,[6] less than three years after the release of its predecessor, Windows Vista. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time.
Unlike its predecessor, Windows Vista, which introduced a large number of new features, Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware which Windows Vista was not at the time.[7] Presentations given by Microsoft in 2008 focused on multi-touch support, a redesigned Windows shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup,[8] and performance improvements. Some standard applications that have been included with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, and Windows Photo Gallery, are not included in Windows 7;[9][10] most are instead offered separately at no charge as part of the Windows Live Essentials suite
WheWindows 7 includes a number of new features, such as advances in touch and handwriting recognition, support for virtual hard disks, improved performance on multi-core processors,[38][39][40][41] improved boot performance, DirectAccess, and kernel improvements. Windows 7 adds support for systems using multiple heterogeneous graphics cards from different vendors (Heterogeneous Multi-adapter), a new version of Windows Media Center,[42] a Gadget for Windows Media Center, improved media features, the XPS Essentials Pack and Windows PowerShell being included, and a redesigned Calculator with multiline capabilities including Programmer and Statistics modes along with unit conversion. Many new items have been added to the Control Panel, including ClearType Text Tuner, Display Color Calibration Wizard, Gadgets, Recovery, Troubleshooting, Workspaces Center, Location and Other Sensors, Credential Manager, Biometric Devices, System Icons, and Display.[43] Windows Security Center has been renamed to Windows Action Center (Windows Health Center and Windows Solution Center in earlier builds), which encompasses both security and maintenance of the computer. Readyboost on 32bit editions now supports up to 256 Gigabytes of extra allocation. The default setting for User Account Control in Windows 7 has been criticized for allowing untrusted software to be launched with elevated privileges without a prompt by exploiting a trusted application.[44] Microsoft's Windows kernel engineer Mark Russinovich acknowledged the problem, but noted that malware can also compromise a system when users agree to a prompt.[45] Windows 7 also supports images in the RAW image format through the addition of Windows Imaging Component-enabled image decoders, which enables raw image thumbnails, previewing and metadata display in Windows Explorer, plus full-size viewing and slideshows in Windows Photo Viewer and Window Media Center.[46]
The taskbar has seen the biggest visual changes, where the Quick Launch toolbar has been replaced with the "Superbar" allowing applications to be pinned to the taskbar. Buttons for pinned applications are integrated with the task buttons. These buttons also enable the Jump Lists feature to allow easy access to common tasks.[47] The revamped taskbar also allows the reordering of taskbar buttons. To the far right of the system clock is a small rectangular button that serves as the Show desktop icon. This button is part of the new feature in Windows 7 called Aero Peek. Hovering over this button makes all visible windows transparent for a quick look at the desktop.[48] In touch-enabled displays such as touch screens, tablet PCs, etc., this button is
slightly wider to accommodate being pressed with a finger.[49] Clicking this button minimizes all windows, and clicking it a second time restores them. Additionally, there is a feature named Aero Snap, that automatically maximizes a window when it is dragged to the top of the screen.[50] Dragging windows to the left/right edges of the screen allows users to snap documents or files on either side of the screen for comparison between windows. When a user moves windows that were maximized using Aero Snap, the system restores their previous state automatically. This functionality is also accomplished with keyboard shortcuts. Unlike in Windows Vista, window borders and the taskbar do not turn opaque when a window is maximized with

Windows Vista developed features and functionalities not present in its predecessors.
[edit] End-user
- Windows Aero: The new hardware-based graphical user interface is named Windows Aero, which Jim Allchin stated is an acronym for Authentic, Energetic, Reflective, and Open.[21] Microsoft intended the new interface to be cleaner and more aesthetically pleasing than those of previous Windows versions, including new transparencies, live thumbnails, live icons, and animations, thus providing a new level of eye candy. Laptop users report, however, that enabling Aero shortens battery life.[22][23]
- Windows Shell: The new Windows shell differs significantly from the shell in Windows XP, offering a new range of organization, navigation, and search capabilities. Windows Explorer's task pane has been removed, integrating the relevant task options into the toolbar. A "Favorite links" pane has been added, enabling one-click access to common directories. The address bar has been replaced with a breadcrumb navigation system. The preview pane allows users to see thumbnails of various files and view the contents of documents. The details pane shows information such as file size and type, and allows viewing and editing of embedded tags in supported file formats. The Start menu has changed as well; it no longer uses ever-expanding boxes when navigating through Programs. The word "Start" itself has been removed in favor of a blue Windows Pearl.
- Instant Search (also known as search as you type) : Windows Vista features a new way of searching called Instant Search, which is significantly faster and more in-depth (content-based) than the search features found in any of the previous versions of Windows.[24]
- Windows Sidebar: A transparent panel anchored to the side of the screen where a user can place Desktop Gadgets, which are small applets designed for a specialized purpose (such as displaying the weather or sports scores). Gadgets can also be placed on other parts of the desktop.
- Windows Internet Explorer 7: New user interface, tabbed browsing, RSS, a search box, improved printing,[25] Page Zoom, Quick Tabs (thumbnails of all open tabs), Anti-Phishing filter, a number of new security protection features, Internationalized Domain Name support (IDN), and improved web standards support. IE7 in Windows Vista runs in isolation from other applications in the operating system (protected mode); exploits and malicious software are restricted from writing to any location beyond Temporary Internet Files without explicit user consent.
- Windows Media Player 11, a major revamp of Microsoft's program for playing and organizing music and video. New features in this version include word wheeling (incremental search or "search as you type"), a new GUI for the media library, photo display and organization, the ability to share music libraries over a network with other Windows Vista machines, Xbox 360 integration, and support for other Media Center Extenders.
- Backup and Restore Center: Includes a backup and restore application that gives users the ability to schedule periodic backups of files on their computer, as well as recovery from previous backups. Backups are incremental, storing only the changes each time, minimizing disk usage. It also features Complete PC Backup (available only in the Ultimate, Business, and Enterprise versions) which backs up an entire computer as an image onto a hard disk or DVD. Complete PC Backup can automatically recreate a machine setup onto new hardware or hard disk in case of any hardware failures. Complete PC Restore can be initiated from within Windows Vista or from the Windows Vista installation CD in the event the PC is so corrupt that it cannot start up normally from the hard disk.
- Windows Mail: A replacement for Outlook Express that includes a new mail store that improves stability,[26] and features integrated Instant Search. It has the Phishing Filter like IE7 and Junk mail filtering that is enhanced through regular updates via Windows Update.[27]
- Windows Calendar is a new calendar and task application.
- Windows Photo Gallery, a photo and movie library management application. It can import from digital cameras, tag and rate individual items, adjust colors and exposure, create and display slideshows (with pan and fade effects) and burn slideshows to DVD.
- Windows DVD Maker, a companion program to Windows Movie Maker that provides the ability to create video DVDs based on a user's content. Users can design a DVD with title, menu, video, soundtrack, pan and zoom motion effects on pictures or slides.
- Windows Media Center, which was previously exclusively bundled in a separate version of Windows XP, known as Windows XP Media Center Edition, has been incorporated into the Home Premium and Ultimate editions of Windows Vista.
- Games and Games Explorer: Games included with Windows have been modified to showcase Vista's graphics capabilities. New games are Chess Titans, Mahjong Titans and Purble Place. A new Games Explorer special folder contains shortcuts and information to all games on the user's computer.
- Windows Mobility Center is a control panel that centralizes the most relevant information related to mobile computing (brightness, sound, battery level / power scheme selection, wireless network, screen orientation, presentation settings, etc.).
- Windows Meeting Space replaces NetMeeting. Users can share applications (or their entire desktop) with other users on the local network, or over the Internet using peer-to-peer technology (higher versions than Starter and Home Basic can take advantage of hosting capabilities, Starter and Home Basic editions are limited to "join" mode only)
- Shadow Copy automatically creates daily backup copies of files and folders. Users can also create "shadow copies" by setting a System Protection Point using the System Protection tab in the System control panel. The user can be presented multiple versions of a file throughout a limited history and be allowed to restore, delete, or copy those versions. This feature is available only in the Business, Enterprise, and Ultimate editions of Windows Vista and is inherited from Windows Server 2003.[28]
- Windows Update: Software and security updates have been simplified,[29] now operating solely via a control panel instead of as a web application. Windows Mail's spam filter and Windows Defender's definitions are updated automatically via Windows Update. Users who choose the recommended setting for Automatic Updates will have the latest drivers installed and available when they add a new device.
- Parental controls: Allows administrators to control which websites, programs and games each Limited user can use and install. This feature is not included in the Business or Enterprise editions of Vista.
- Windows SideShow: Enables the auxiliary displays on newer laptops or on supported Windows Mobile devices. It is meant to be used to display device gadgets while the computer is on or off.
- Speech recognition is integrated into Vista.[30] It features a redesigned user interface and configurable command-and-control commands. Unlike the Office 2003 version, which works only in Office and WordPad, Speech Recognition in Windows Vista works for any accessible application. In addition, it currently supports several languages: British and American English, Spanish, French, German, Chinese (Traditional and Simplified) and Japanese.
- New fonts, including several designed for screen reading, and improved Chinese (Yahei, JhengHei), Japanese (Meiryo) and Korean (Malgun) fonts. ClearType has also been enhanced and enabled by default.
- Improved audio controls allow the system-wide volume or volume of individual audio devices and even individual applications to be controlled separately. New audio functionalities such as Room Correction, Bass Management, Speaker Fill and Headphone virtualization have also been incorporated.
- Problem Reports and Solutions, a control panel which allows users to view previously sent problems and any solutions or additional information that is available.
- Windows System Assessment Tool is a tool used to benchmark system performance. Software such as games can retrieve this rating and modify its own behavior at runtime to improve performance. The benchmark tests CPU, RAM, 2-D and 3-D graphics acceleration, graphics memory and hard disk space.[31][32]
- Windows Ultimate Extras: The Ultimate edition of Windows Vista provides, via Windows Update, access to some additional features. These are a collection of additional MUI language packs, Texas Hold 'Em (a Poker game) and Microsoft Tinker (a strategy game where the character is a robot), BitLocker and EFS enhancements which allow users to back up their encryption key online in a Digital Locker, and Windows Dreamscene, which enables the use of videos in MPEG and WMV formats as the desktop background. On April 21, 2008, Microsoft launched two more Ultimate Extras; three new Windows sound schemes, and a content pack for Dreamscene. Various DreamScene Content Packs have been released since the final version of DreamScene was released.
- Reliability and Performance Monitor includes various tools for tuning and monitoring system performance and resources activities of CPU, disks, network, memory and other resources. It shows the operations on files, the opened connections, etc.
