Reference excerpt

Microsoft Windows was announced by Bill Gates on November 10, 1983, 2 years before it was first released. Microsoft introduced Windows as a graphical user interface for MS-DOS, which had been introduced two years earlier, on August 12, 1981. The product line evolved in the 1990s from an operating environment into a fully complete, modern operating system over two lines of development, each with their own separate codebase. The first versions of Windows (1.0 through 2.0) were graphical shells that ran from MS-DOS. The Windows 3x series in its 386 Enhanced Mode used MS-DOS as a bootloader and displaced it as a virtual machine monitor. Windows 95 also had a significant amount of 16-bit code ported from Windows 3.1. Windows 95 introduced multiple features that have been part of the product ever since, including the Start menu, the taskbar, and Windows Explorer (renamed File Explorer in Windows 8). In 1997, Microsoft released Internet Explorer 4 which included the (at the time controversial) Windows Desktop Update. It aimed to integrate Internet Explorer and the web into the user interface and also brought new features into Windows, such as the ability to display JPEG images as the desktop wallpaper and single window navigation in Windows Explorer. In 1998, Microsoft released Windows 98, which also included the Windows Desktop Update and Internet Explorer 4 by default. The inclusion of Internet Explorer 4 and the Desktop Update led to an antitrust case in the United States. Windows 98 included USB support out of the box, and also plug and play, which allows devices to work when plugged in without requiring a system reboot or manual configuration. Windows Me, the last DOS-based version of Windows, was aimed at consumers and released in 2000. It introduced System Restore, Help and Support Center, updated versions of the Disk Defragmenter and other system tools. In 1993, Microsoft released Windows NT 3.1, the first version of the newly developed Windows NT operating system, followed by Windows NT 3.5 in 1994, and Windows NT 3.51 in 1995. "NT" is an initialism for "New Technology". Unlike the Windows 9x series of operating systems, it was a fully 32-bit operating system. NT 3.1 introduced NTFS, a file system designed to replace the older File Allocation Table (FAT) which was used by DOS and the DOS-based Windows operating systems. In 1996, Windows NT 4.0 was released, which included a fully 32-bit version of Windows Explorer written specifically for it, making the operating system work like Windows 95. Windows NT was originally designed to be used on high-end systems and servers, but with the release of Windows 2000, many consumer-oriented features from Windows 95 and Windows 98 were included, such as the Windows Desktop Update, Internet Explorer 5, USB support and Windows Media Player. These consumer-oriented features were further extended in Windows XP in 2001, which included a new visual style called Luna, a more user-friendly interface, updated versions of Windows Media Player and Internet Explorer 6 by default, and extended features from Windows Me, such as the Help and Support Center and System Restore. Windows Vista, which was released in 2007, focused on securing the Windows operating system against computer viruses and other malicious software by introducing features such as User Account Control. New features include Windows Aero, updated versions of the standard games (e.g. Solitaire), Windows Movie Maker, and Windows Mail to replace Outlook Express. Despite this, Windows Vista received negative reviews from technology publications, which cited performance issues on older hardware and higher system requirements. Windows 7 followed in 2009 nearly three years after its launch, and despite it technically having higher system requirements, reviewers noted that it ran better than Windows Vista. Windows 7 removed many applications, such as Windows Movie Maker, Windows Photo Gallery and Windows Mail, instead requiring users to download separate Windows Live Essentials to gain some of those features and other online services. Windows 8, which was released in 2012, introduced many controversial changes, such as the replacement of the Start menu with the Start Screen, the removal of the Aero interface in favor of a flat, colored interface as well as the introduction of "Metro" apps (later renamed to Universal Windows Platform (UWP) apps), and the Charms Bar user interface element, all of which received considerable criticism from reviewers. Windows 8.1, a free upgrade to Windows 8, was released in 2013. The following version of Windows, Windows 10, which was released in 2015, reintroduced the Start menu and added the ability to run Universal Windows Platform apps in a window instead of always in full screen. Windows 10 was generally well-received, with many reviewers stating that Windows 10 is what Windows 8 should have been. The latest version of Windows, Windows 11, was released to the general public on October 5, 2021. Windows 11 incorporates a redesigned user interface, including a new Start menu, a visual style featuring rounded corners, and a new layout for the Microsoft Store, and also included Microsoft Edge by default.

Windows 1.0

Windows development started back in 1983, and it was a joke in the industry ... Betting the company on it was a big, big bet. Windows 1.0, (series 1.01, 1.02, 1.03, and 1.04) the first independent version of Microsoft Windows, released on November 20, 1985, achieved little popularity. The project was briefly codenamed "Interface Manager" before the windowing system was implemented—contrary to popular belief that it was the original name for Windows and Rowland Hanson, the head of marketing at Microsoft, convinced the company that the name Windows would be more appealing to customers.

Worked examples

Example 1 — a first encounter with Microsoft Windows version history

Start with the simplest possible case. Write down what Microsoft Windows version history claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Microsoft Windows version history before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Microsoft Windows version history ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Microsoft Windows version history

In research: Microsoft Windows version history appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Microsoft Windows version history in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Microsoft Windows version history is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of Microsoft, History of software, Lists of operating systems, so understanding it makes those chapters shorter.
In everyday life: Look for Microsoft Windows version history outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
