Windows 8 is a major release of the Windows NT operating system developed by Microsoft. It was released to manufacturing on August 1, ; it was subsequently made available for download via MSDN and TechNet on August 15, ,  and later to retail on October 26, Windows 8 introduced major changes to the operating system’s platform and user interface intended to improve its user experience on tablets , where Windows was now competing with mobile operating systems , including Android and iOS.
Windows 8 added support for USB 3. Additional security features were introduced, such as built-in antivirus software , integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices. Windows 8 was released to a mixed critical reception. Although reaction towards its performance improvements, security enhancements, and improved support for touchscreen devices was positive, the new user interface of the operating system was widely criticized for being potentially confusing and difficult to learn, especially when used with a keyboard and mouse instead of a touchscreen.
Despite these shortcomings, 60 million Windows 8 licenses were sold through January , a number that included both upgrades and sales to OEMs for new PCs.
Microsoft released Windows 8. Windows 8 was ultimately succeeded by Windows 10 in July Windows 8 development started before Windows 7 had shipped in Windows division president Steven Sinofsky demonstrated an early build of the port on prototype devices, while Microsoft CEO Steve Ballmer announced the company’s goal for Windows to be “everywhere on every kind of device without compromise.
The earliest available build of Windows 8 is build , compiled in January In addition, there were references to Windows 8 in this build. In late , an optional 3D desktop user interface for high-end systems named “Wind” was rumored. Two milestone releases of Windows 8 and one of Windows Server leaked to the general public.
Milestone 1, Build , was leaked on April 12, It was also probably the first appearance of the Metro-style font, and its wallpaper had the text shhh. However, its detailed build number reveals that the build was created on September 22, In , it was discovered that Metro existed in this build, after enabling the ‘Redpill’.
The start screen was very primitive, being a white screen with gray tiles. The charms bar was also included, but was unusable. The OS still reads as “Windows 7”. Milestone 2, Build , was leaked on April 25, The traditional Blue Screen of Death BSoD was replaced by a new black screen,  although it was later reverted to a different blue color.
This build introduced a new ribbon in Windows Explorer. The “Windows 7” logo was temporarily replaced with text displaying “Microsoft Confidential”. Both builds and leaked alongside Windows Server build On June 17, , build bit edition was leaked.
It introduced a new boot screen featuring the same Betta fish as the default Windows 7 Beta wallpaper, which was later replaced, and the circling dots as featured in the final although the final version comes with smaller circling dots throbber. It also had the text Welcome below them, although this was scrapped. It is worth mentioning that most of these leaks “hid” the main Metro UI features that were to come in tweak known as Redlock in order to prevent relevant leaks.
It also worked on the Developer Preview. This build also leaked in the x86 architecture as a debug build, with the setup having a slight change – the theme was now Windows Basic in setup, rather than Classic. Build was the first build to remove the User Tile. A new wallpaper was introduced and Metro was updated to be more like the final version of Windows 8. The “Building Windows 8” blog launched on August 15, , featuring details surrounding Windows 8’s features and its development process.
As Windows 8 transitioned away from being in the Milestone phase of development, the Developer Preview was beginning to take shape. Build changed the branding to Windows Developer Preview and was the last build to use Windows 7 branding anywhere. Build introduced several changes to the interface and small stability improvements. Metro was updated to be more like the Metro in Developer Preview although it was still different and a new wallpaper was introduced. Microsoft unveiled more Windows 8 features and improvements on the first day of the Build conference on September 13, A Samsung tablet running the build was also distributed to conference attendees.
The build was released for download later that day in standard bit and bit variants, plus a special bit variant which included SDKs and developer tools Visual Studio Express and Expression Blend for developing Metro-style apps. Build is the earliest leaked post-Developer Preview build. This build disables Redpill, and Metro can be manually enabled through the editing of system files. Build removed Redpill, and Metro was enabled by default with no way to disable it although build is being distributed by Microsoft with Redpill already applied and can be disabled with a registry key .
Build featured new branding – Windows 8 Beta. The Consumer Preview wallpapers have now been added, and the setup color has been changed to be the same as the final Consumer Preview. Build is largely the same as , although it removes the Start Button from the taskbar. While the start button could be removed in early Milestone 2 and this persisted through Windows 8 development with a registry key, this build disabled it by default with no way to turn it back on.
The branding is now identical to the Consumer Preview. On February 17, , Microsoft unveiled a new logo to be adopted for Windows 8. Designed by Pentagram partner Paula Scher , the Windows logo was changed to resemble a set of four window panes. Additionally, the entire logo is now rendered in a single solid color. Alongside other changes, the build brought over the big change from build removing the Start button from the taskbar for the first time in a public build since its debut on Windows 95 ; according to Windows manager Chaitanya Sareen, the Start button was removed to reflect their view that on Windows 8, the desktop was an “app” itself, and not the primary interface of the operating system.
Development on the third and final preview of Windows 8, the Release Preview, began shortly after Consumer Preview note: build was compiled on February 8, , before  .
Build was a build in between the Consumer and Release Previews. This build includes a new default wallpaper and several changes, such as the new logo replacing the old one and appearing in the About Windows dialog box.
Many other builds may exist or were released until Japan’s Developers Day conference when Steven Sinofsky announced that Windows 8 Release Preview build would be released during the first week of June. Build is the last available build to contain Aero. It was dropped in build and seen for two builds after Build removed Desktop Gadgets. It was identical to , which removed Aero. Build was shared online in December , and was identical to the RTM with the exception of the timebomb and missing apps.
On August 1, , Windows 8 build  was released to manufacturing with the build number 6. Relatively few changes were made from the Release Preview to the final version; these included updated versions of its pre-loaded apps, the renaming of Windows Explorer to File Explorer, the replacement of the Aero Glass theme from Windows Vista and 7 with a new flat and solid-color theme as seen in build , and the addition of new background options for the Start screen, lock screen, and desktop.
Microsoft indicated that due to improvements to its testing infrastructure, general improvements of this nature are to be released more frequently through Windows Update instead of being relegated to OEMs and service packs only. Microsoft began an advertising campaign centered around Windows 8 and its Surface tablet in October , starting with its first television advertisement premiering on October 14, In an effort to make retail displays of Windows 8 devices more “personal”, Microsoft also developed a character known in English-speaking markets as “Allison Brown”, whose fictional profile including personal photos, contacts, and emails is also featured on demonstration units of Windows 8 devices.
In May , Microsoft launched a new television campaign for Windows 8 illustrating the capabilities and pricing of Windows 8 tablets in comparison to the iPad , which featured the voice of Siri remarking on the iPad’s limitations in a parody of Apple’s ” Get a Mac ” advertisements.
New features and functionality in Windows 8 include a faster startup through UEFI integration and the new “Hybrid Boot” mode which hibernates the Windows kernel on shutdown to speed up the subsequent boot ,  a new lock screen with a clock and notifications,  and the ability for enterprise users to create live USB variants of Windows known as Windows To Go.
Windows Explorer , which has been renamed File Explorer, now includes a ribbon in place of the command bar. File operation dialog boxes have been updated to provide more detailed statistics, the ability to pause file transfers, and improvements in the ability to manage conflicts when copying files.
Task Manager has been redesigned, including a new processes tab with the option to display fewer or more details of running applications and background processes, a heat map using different colors indicating the level of resource usage, network and disk counters, grouping by process type e. New security features in Windows 8 include two new authentication methods tailored towards touchscreens PINs and picture passwords ,  the addition of antivirus capabilities to Windows Defender bringing it in parity with Microsoft Security Essentials.
Windows 8 supports a feature of the UEFI specification known as “Secure boot”, which uses a public-key infrastructure to verify the integrity of the operating system and prevent unauthorized programs such as bootkits from infecting the device’s boot process.
Windows 8 provides heavier integration with online services from Microsoft and others. A user can now log into Windows with a Microsoft account , which can be used to access services and synchronize applications and settings between devices.
Windows 8 also ships with a client app for Microsoft’s SkyDrive cloud storage service, which also allows apps to save files directly to SkyDrive. A SkyDrive client for the desktop and File Explorer is not included in Windows 8, and must be downloaded separately. Games can integrate into an Xbox Live hub app, which also allows users to view their profile and Gamerscore. Internet Explorer 10 is included as both a desktop program and a touch-optimized app, and includes increased support for HTML5 , CSS3 , and hardware acceleration.
The Internet Explorer app does not support plugins or ActiveX components, but includes a variant of Adobe Flash Player that is optimized for touch and low power usage. Initially, Adobe Flash would only work on sites included on a “Compatibility View” whitelist ; however, after feedback from users and additional compatibility tests, an update in March changed this behavior to use a smaller blacklist of sites with known compatibility issues instead, allowing Flash to be used on most sites by default.
Windows 8 also incorporates improved support for mobile broadband ; the operating system can now detect the insertion of a SIM card and automatically configure connection settings including APNs and carrier branding , and reduce its Internet usage to conserve bandwidth on metered networks. Windows 8 also adds an integrated airplane mode setting to globally disable all wireless connectivity as well. Carriers can also offer account management systems through Windows Store apps, which can be automatically installed as a part of the connection process and offer usage statistics on their respective tile.
Windows 8 introduces a new style of application, Windows Store apps. According to Microsoft developer Jensen Harris, these apps are to be optimized for touchscreen environments and are more specialized than current desktop applications. Apps can run either in a full-screen mode or be snapped to the side of a screen.
Apps can use “contracts”; a collection of hooks to provide common functionality that can integrate with other apps, including search and sharing.
Components may be compiled as Windows Runtime Components, permitting consumption by all compatible languages. Retail variants of Windows 8 are only able to install these apps through Windows Store — a namesake distribution platform that offers both apps, and listings for desktop programs certified for comparability with Windows 8. The term “Immersive app” had been used internally by Microsoft developers to refer to the apps prior to the first official presentation of Windows 8, after which they were referred to as “Metro-style apps” in reference to the Metro design language.
The term was phased out in August ; a Microsoft spokesperson denied rumors that the change was related to a potential trademark issue, and stated that “Metro” was only a codename that would be replaced prior to Windows 8’s release. In an interview on September 12, , Soma Somasegar vice president of Microsoft’s development software division confirmed that “Windows Store apps” would be the official term for the apps. Exceptions to the restrictions faced by Windows Store apps are given to web browsers.
The user’s default browser can distribute a Metro-style web browser in the same package as the desktop variant, which has access to functionality unavailable to other apps, such as being able to permanently run in the background, use multiple background processes, and use Windows API code instead of WinRT allowing for code to be re-used with the desktop variant, while still taking advantage of features available to Windows Store apps, such as charms.
