Microsoft Windows was announced by Bill Gates on 10 November 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. 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.
Microsoft Windows is a product line of proprietary graphical operating systems developed and marketed by Microsoft. It is grouped into families and sub-families that cater to particular sectors of the computing industry -- Windows (unqualified) for a consumer or corporate workstation, Windows Server for a server and Windows IoT for an embedded system. Defunct families include Windows 9x, Windows Mobile, Windows Phone, and Windows Embedded Compact.
Paint is a simple raster graphics editor that has been included with all versions of Microsoft Windows. The program opens, modifies and saves image files in Windows bitmap (BMP), JPEG, GIF, PNG, and single-page TIFF formats. The program can be in color mode or two-color black-and-white, but there is no grayscale mode. For its simplicity and wide availability, it rapidly became one of the most used Windows applications, introducing many to painting on a computer for the first time.
Windows 7 is a major release of the Windows NT operating system developed by Microsoft. It was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009. It is the successor to Windows Vista, released nearly three years earlier. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time. Windows 7 remained an operating system for use on personal computers, including home and business desktops, laptops, tablet PCs and media center PCs, and itself was replaced in November 2012 by Windows 8, the name spanning more than three years of the product.
The Windows logo key is a keyboard key which was originally introduced on Microsoft's Natural Keyboard in 1994. This key became a standard key on PC keyboards. In Windows, pressing the key brings up the start menu. Ctrl+Esc performs the same function, in case the keyboard lacks this key.
The Start menu is a graphical user interface element that has been part of Microsoft Windows since Windows 95, providing a means of opening programs and performing other functions in the Windows shell. The Start menu, and the Taskbar on which it appears, were created and named in 1993 by Daniel Oran, a program manager at Microsoft who had previously collaborated on great ape language research with the behavioral psychologist B.F. Skinner at Harvard.
Compared with previous versions of Microsoft Windows, features new to Windows Vista are very numerous, covering most aspects of the operating system, including additional management features, new aspects of security and safety, new I/O technologies, new networking features, and new technical features. Windows Vista also removed some others.
Windows 8 is a major release of the Windows NT operating system developed by Microsoft. It was released to manufacturing on August 1, 2012, and was made available for download via MSDN and TechNet on August 15, 2012. Nearly three months after its initial release, it finally made its first retail appearance on October 26, 2012.
Windows 10 is a major release of Microsoft's Windows NT operating system. It is the direct successor to Windows 8.1, which was released nearly two years earlier. It was released to manufacturing on July 15, 2015, and later to retail on July 29, 2015. Windows 10 was made available for download via MSDN and TechNet, as a free upgrade for retail copies of Windows 8 and Windows 8.1 users via the Microsoft Store, and to Windows 7 users via Windows Update. Windows 10 receives new builds on an ongoing basis, which are available at no additional cost to users, in addition to additional test builds of Windows 10, which are available to Windows Insiders. Devices in enterprise environments can receive these updates at a slower pace, or use long-term support milestones that only receive critical updates, such as security patches, over their ten-year lifespan of extended support. In June 2021, Microsoft announced that support for Windows 10 editions which are not in the Long-Term Servicing Channel (LTSC) will end on October 14, 2025.
Windows 10 Mobile was a mobile operating system developed by Microsoft. First released in 2015, it is a successor to Windows Phone 8.1, but was marketed by Microsoft as being an edition of its PC operating system Windows 10.
Windows Insider is an open software testing program by Microsoft that allows users globally who own a valid license of Windows 11, Windows 10, or Windows Server to register for pre-release builds of the operating system previously only accessible to software developers.
Windows 10 has several editions, all with varying feature sets, use cases, or intended devices. Certain editions are distributed only on devices directly from an original equipment manufacturer (OEM), while editions such as Enterprise and Education are only available through volume licensing channels. Microsoft also makes editions of Windows 10 available to device manufacturers for use on specific classes of devices, including IoT devices, and previously marketed Windows 10 Mobile for smartphones.
Windows 10 introduced a number of new elements, including the option to use a touch-optimized interface or a traditional desktop interface similar to that of Windows 7 along with live tiles from Windows 8. However, unlike previous versions of Windows, where most, if not all, major features for that release were completed by its RTM, Windows 10 continues to receive major features and changes beyond its initial release to market. Microsoft describes Windows 10 as an "operating system as a service" that will receive ongoing updates to its features and functionality. This is supplemented with the ability for enterprise environments to receive non-critical updates at a slower pace, and to use long-term support milestones that will only receive critical updates, such as security patches, over their ten-year lifespan of support.
Windows 10 is a major release of the Windows NT operating system developed by Microsoft. Microsoft described Windows 10 as an "operating system as a service" that would receive ongoing updates to its features and functionality, augmented with the ability for enterprise environments to receive non-critical updates at a slower pace or use long-term support milestones that will only receive critical updates, such as security patches, over their five-year lifespan of mainstream support. It was released in July 2015.
Tips is the latest of a series of tutorial hubs in Microsoft Windows that provides information about using features. Information is presented as screenshots, text descriptions, videos, and web links. As Windows upgrades have traditionally been drastic, each version since Windows 95 has had its own tutorial app, and the name has changed frequently. Notably, the feature list shown has tended to expand as newer versions of Windows are released and the most recently released tutorial receives updates through the Microsoft Store, allowing it to receive updates more frequently than Windows itself is upgraded.
Windows 11 is the latest major release of Microsoft's Windows NT operating system, released on October 5, 2021. It succeeded Windows 10 (2015) and is available for free for any Windows 10 devices that meet the new Windows 11 system requirements.
Windows 11 is a major release of the Windows NT operating system and is the successor to Windows 10. It introduces new features such as a redesigned interface, new productivity and social features, and updates to security and accessibility, along with improvements to performance.
