Windows 8 in the context of Xbox Music

The Microsoft Store (formerly known as the Windows Store) is a digital distribution platform operated by Microsoft. It was created as an app store for Windows 8 as the primary means of distributing Universal Windows Platform apps. With Windows 10 1803, Microsoft merged its other distribution platforms (Windows Marketplace, Windows Phone Store, Xbox Music, Xbox Video, Xbox Store, and a web storefront also known as "Microsoft Store") into Microsoft Store, making it a unified distribution point for apps, console games, and digital videos. Digital music was included until the end of 2017, and E-books were included until 2019.

As with other similar platforms, such as the Google Play and Mac App Store, Microsoft Store is curated, and apps must be certified for compatibility and content. In addition to the user-facing Microsoft Store client, the store has a developer portal with which developers can interact. Microsoft takes 5–15% of the sale price for apps and 30% on Xbox games. Prior to January 1, 2015, this cut was reduced to 20% after the developer's profits reached $25,000. In 2021, 669,000 apps were available in the store. Categories containing the largest number of apps are "Books and Reference", "Education", "Entertainment", and "Games". The majority of the app developers have one app.

Windows 10 is a major release of Microsoft's Windows NT operating system. The successor to Windows 8.1, it was released to manufacturing on July 15, 2015, to retail on July 29, 2015, and was a free upgrade to users of Windows 7, 8, and 8.1. Its server counterparts are Windows Server 2016, 2019, and 2022. It was succeeded by Windows 11 in October 2021.

In contrast to the tablet-oriented approach of its predecessor, Windows 10 returned to a desktop-oriented interface in line with previous versions of Windows and reintroduced the Start menu. Other features included the Cortana virtual assistant, Task View and virtual desktops, Action Center, biometric authentication through Windows Hello, an improved Settings component, Xbox Live integration, and DirectX 12. Also, Microsoft Edge was introduced, deprecating Internet Explorer. Unlike previous NT releases, Windows 10 received free feature updates on an ongoing basis. Alternatively, enterprise environments can use long-term support milestones that receive only critical and security updates. An ARM version of Windows 10 was released in 2018.

Microsoft Edge is a proprietary cross-platform web browser created by Microsoft and based on the Chromium open-source project, superseding Edge Legacy. In Windows 11, Edge is the only browser available from Microsoft. However, a bypass is available to open Internet Explorer.

First made available only for Android and iOS in 2017, in late 2018, Microsoft announced it would completely rebuild Edge as a Chromium-based browser with Blink and V8 engines, which allowed the browser to be ported from Windows 10 to macOS. The new Edge was publicly released in January 2020, and on Xbox as well as Linux in 2021. Edge was also available on Windows 7 and 8/8.1 until early 2023.

Universal Windows Platform (UWP) apps (formerly named Windows Store apps, Metro-style apps and Modern apps) are applications that are built on the Universal Windows Platform. They are primarily purchased and downloaded via the Microsoft Store, Microsoft's digital application storefront and can be used across all compatible Microsoft Windows devices since Windows 8. UWP stopped adding new features in October 2021, but toolchain updates continue to be made.

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. It sold over 630 million copies before it was succeeded by Windows 8 in October 2012.

Extended support ended on January 14, 2020, over 10 years after the release of Windows 7; the operating system ceased receiving further updates after that date. A paid support program was available for enterprises, providing security updates for Windows 7 for up to three years since the official end of life.

Windows Phone (WP) is a discontinued mobile operating system developed by Microsoft for smartphones as the replacement successor to Windows Mobile and Zune. Windows Phone featured a new user interface derived from the Metro design language. Unlike Windows Mobile, it was primarily aimed at the consumer market rather than the enterprise market.

It was first launched in October 2010 with Windows Phone 7. Windows Phone 8 succeeded it in 2012, replacing the Windows CE-based kernel of Windows Phone 7 with the Windows NT kernel used by the PC versions of Windows (and, in particular, a large amount of internal components from Windows 8). Due to these changes, the OS was incompatible with all existing Windows Phone 7 devices, although it still supported apps originally developed for Windows Phone 7. In 2014, Microsoft released the Windows Phone 8.1 update, which introduced the Cortana virtual assistant, and Windows Runtime platform support to create cross-platform apps between Windows PCs and Windows Phone.

Windows 8.1 is a release of the Windows NT operating system based on Windows 8 developed by Microsoft. It was released to manufacturing on August 27, 2013, and broadly released for retail sale on October 17, 2013, about a year after the retail release of its predecessor, and succeeded by Windows 10 on July 29, 2015. Windows 8.1 was made available for download via MSDN and Technet and available as a free upgrade for retail copies of Windows 8 and Windows RT users via the Windows Store. A server version, Windows Server 2012 R2, was released on October 18, 2013.

Windows 8.1 aimed to address complaints of Windows 8 users and reviewers on launch. Enhancements include an improved Start screen, additional snap views, additional bundled apps, tighter OneDrive (formerly SkyDrive) integration, Internet Explorer 11 (IE11), a Bing-powered unified search system, restoration of a visible Start button on the taskbar, and the ability to restore the previous behavior of opening the user's desktop on login instead of the Start screen. Windows 8.1 also added support for then emerging technologies like high-resolution displays, 3D printing, Wi-Fi Direct, and Miracast streaming, as well as the ReFS file system.

The Start menu (called Start screen in Windows 8, 8.1, Server 2012, and Server 2012 R2) 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.

The Start menu was renamed Start screen in Windows 8, before returning to its original name with Windows 10. It has been co-opted by some operating systems (like ReactOS) and Linux desktop environments for providing a more Windows-like experience, and as such is, for example, present in KDE, with the name of Kickoff Application Launcher, and on Xfce with the name of Whisker Menu.

Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh computers) in computing is powering down a computer while retaining its state. When hibernation begins, the computer saves the contents of its random access memory (RAM) to a hard disk or other non-volatile storage. When the computer is turned on the RAM is restored and the computer is exactly as it was before entering hibernation. Hibernation was first implemented in 1992 and patented by Compaq Computer Corporation in Houston, Texas.

Microsoft's Windows 8, Windows 8.1, Windows 10 and Windows 11 employ a type of hibernation (Fast Startup) by default when shutting down.
