Thousands of Developers Achieve Guinness World Record at Windows AppFest

Thousands of Developers Achieve Guinness World Record at Windows AppFest Microsoft creates history; makes Official Guinness World Record by bringing together 2567 developers at a single location to compete in Windows AppFest—a non-stop 18 hours coding marathon for developing Windows 8 applications.

List of features removed in Windows 8

Aside from the removal of the Start menu, several notable features have been removed in Windows 8. Support for playing DVDs has been removed from Windows Media Player due to the cost of licensing the necessary decoders (especially for devices which do not include optical disc drives at all) and the prevalence of streaming services such as Netflix. For the same reasons, Windows Media Center will no longer be included by default on Windows 8 as well, but the software (which also includes support for DVD playback) can be added back through the paid "Pro Pack" (for the base version of Windows 8, which also upgrades the system to Windows 8 Pro) or "Media Center Pack" (for Windows 8 Pro) add-ons. Windows 8 will still support third-party DVD playback software. File History, the new backup feature of Windows 8 described above, replaces Backup and Restore, the former backup app, and Previous Versions, a component of Windows Explorer that saves previous versions of changed files. Backup and Restore is deprecated but will continue to work on preset schedule on computers that upgrade from Windows 7 to Windows 8. Previous Versions no longer protects local files, although it is still available to access previous versions of shared files stored on a Windows Server computer. Shadow Copy, the subsystem component based on which these worked, however, is still available for other software to use.

Windows Store and Apps

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 have smaller scope in relation to desktop applications. Apps can run either in a full-screen mode, or be docked directly to the side of a screen. They can provide notifications and a "live tile" on the Start screen for dynamic content. Apps can use "contracts"; a collection of hooks to provide common functionality that can integrate with other apps, such as search and sharing. Apps can also provide integration with other services; for example, the People app can connect to a variety of different social networks and services (such as Facebook), while the Photos app can aggregate photos from services such as Facebook and Flickr. Windows Store apps run within a new set of APIs known as the Windows Runtime, which supports programming languages such as C, C++, VB.NET, C#, along with HTML5 and JavaScript. Depending on the language used, apps written for Windows Runtime can be cross-compatible with both Intel and ARM versions of Windows. To ensure stability and security, apps run within a sandboxed environment, and require permissions to access certain functionality, such as accessing the Internet or a camera. Retail versions of Windows 8 will only be able to install these apps through the Windows Store—a namesake distribution platform which offers both apps and certified desktop applications. Sideloading, or the facility for loading Windows Store apps from outside Windows Store, is provisioned in Windows 8 Enterprise, Windows 8 Pro and Windows RT, albeit in a very limited fashion: Out-of-box sideloading support is only available for Windows 8 Enterprise computers that have joined a Windows domain. Sideloading on Windows RT and Windows 8 Pro computers as well as Windows 8 Enterprise computers without a domain affiliation requires purchase of additional licenses through Microsoft volume licensing outlet. Windows Store apps were originally known as "Metro-style apps" during the development of Windows 8, referring to the Metro design language. The term was reportedly phased out in August 2012; 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 phased out prior to Windows 8's release. Following these reports, the terms "Modern UI-style apps", "Windows 8-style apps"[74] and "Windows Store apps" began to be used by various Microsoft documents and material to refer to the new apps. In an interview on September 12, 2012, Soma Somasegar (vice president of Microsoft's development software division) officially confirmed that "Windows Store apps" would be the official term for the apps.

Interface and desktop of Windows 8

Windows 8 introduces significant changes to the operating system's user interface, many of which are centered towards improving its experience on tablet computers and other touchscreen devices. The new user interface is based on Microsoft's Metro design language, and features a new tile-based Start screen similar to that of Windows Phone, which has replaced the previous Start menu entirely. The Start screen displays a customizable array of tiles linking to various apps and desktop programs, some of which can display constantly updated information and content through "live tiles". As a form of multi-tasking, apps can be snapped to the side of a screen. A vertical toolbar known as the charms bar (accessed by swiping from the right edge of a touchscreen, or pointing the cursor at hotspots in the right corners of a screen) provides access to system and app-related functions, such as search, sharing, device management, settings, and a Start button. The traditional desktop environment for running desktop applications is accessed via a tile on the new Start screen. The Start button on the taskbar has been removed in favor of the Start button on the charms bar and a hotspot in the lower-left corner of the screen. Swiping from the left edge of a touchscreen or clicking in the top-left corner of the screen allows one to switch between apps and the Desktop. Pointing the cursor in the top-left corner of the screen and moving down reveals a thumbnail list of active apps. Aside from the removal of the Start button, the desktop on Windows 8 is similar to that of Windows 7, except that the Aero Glass theme has been replaced by a flatter, solid-colored design inspired by the Metro interface.

Software compatibility of Windows 8

The three desktop editions of Windows 8 are sold in two sub-editions: 32-bit and 64-bit. The 32-bit sub-edition runs on CPUs compatible with x86 architecture 3rd generation (known as IA-32) or newer, and can only run 32-bit programs. The 64-bit sub-edition runs on CPUs compatible with x86 8th generation (known as x86-64, or x64) or newer, and can run 32-bit and 64-bit programs. 32-bit programs and operating system are restricted to supporting only 4 gigabytes of memory while 64-bit systems can theoretically support 2048 gigabytes of memory. 64-bit operating system require a different set of device drivers than those of 32-bit operating systems. The 32-bit edition of Windows 8 is capable of running 16-bit applications, although 16-bit support must be enabled first. 16-bit applications are developed for CPUs compatible with x86 2nd generation, first conceived in 1978. Microsoft started moving away from this architecture since Windows 95. Windows RT, the only edition of Windows 8 for systems with ARM processors, only supports applications included with the system (such as a special version of Office 2013), supplied through Windows Update, or Windows Store apps, to ensure that the system only runs applications that are optimized for the architecture. Windows RT does not support running IA-32 or x64 applications. Windows Store apps can either be cross-compatible between Windows 8 and Windows RT, or compiled to support a specific architecture.

Windows 8 Market performance

Microsoft says that 4 million users upgraded to Windows 8 over the weekend after its release, which CNET says was well below Microsoft's internal projections and have been described inside the company as disappointing. On 27 November 2012, Microsoft announced that it has sold 40 million licenses of Windows 8 in the first month, surpassing the pace of Windows 7. However, according to research firm NPD, sales of devices running Windows in the United States have declined 21 percent compared to the same time period last year. As the holiday shopping season wrapped up, Windows 8 sales continued to lag, even as Apple reported brisk sales.

On 19 February 2012, Microsoft officially unveiled a new Windows logo to be adopted on Windows 8. Designed by Pentagram partner Paula Scher, the logo was changed to resemble a set of four window panes. Additionally, the entire logo is now rendered in a single solid color

Secure boot

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. Despite the security benefits of the feature, Microsoft faced criticism (particularly from free software supporters) for mandating that devices receiving its optional certification for Windows 8 have secure boot enabled by default using a key provided by Microsoft. Concerns were raised that secure boot could prevent or hinder the use of alternate operating systems such as Linux. In response to the criticism, Microsoft developer Tony Mangefeste stated that "At the end of the day, the customer is in control of their PC. Microsoft’s philosophy is to provide customers with the best experience first, and allow them to make decisions themselves." Microsoft's certification requirements eventually revealed that UEFI firmware on x86 systems must allow users to re-configure or turn off secure boot, but that this must not be possible on ARM-based systems (Windows RT). Microsoft faced further criticism for its decision to restrict Windows RT devices by using this functionality, despite it being consistent with other consumer electronics with similar protection measures.No mandate is made regarding the installation of third-party certificates that would enable running alternative software.

Online services and functionality

Windows 8 provides heavier integration with online services from Microsoft and others. A user can now log in to Windows with a Microsoft account, formally known as a Windows Live ID, 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. Bundled multimedia apps are provided under the Xbox brand, including Xbox Music, Xbox Video, and the Xbox SmartGlass companion for use with an Xbox 360 console. Games can integrate into an Xbox Live hub app, which also allows users to view their profile and gamerscore. Other bundled apps provide the ability to link to services such as Flickr and Facebook. 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 version of Adobe Flash Player that is optimized for touch and low power usage, but works only on sites included on a whitelist. The desktop version does not contain these limitations. 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), track and reduce bandwidth use 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 Development history

Windows 8 development started before Windows 7 had shipped in 2009. In late January 2011, at the Consumer Electronics Show (CES), Microsoft announced that Windows 8 would be adding support for ARM microprocessors in addition to the x86 microprocessors from Intel, AMD and VIA Technologies. On 1 June 2011, Microsoft officially unveiled Windows 8's new user interface as well as additional features at the Taipei Computex 2011 in Taipei (Taiwan) by Mike Angiulo and at the D9 conference in California (United States) by Julie Larson-Green and Microsoft's Windows President Steven Sinofsky.The "Building Windows 8" blog launched on 15 August 2011, featuring details surrounding Windows 8's features and its development process. A screenshot of Windows 8 Developer Preview running on a multi-monitor system, showcasing some features Microsoft unveiled new Windows 8 features and improvements on the first day of the BUILD conference on 13 September 2011. Microsoft released Windows 8 Developer Preview (build 8102) the same day, which included SDKs and developer tools (such as Visual Studio Express and Expression Blend) for developing applications for Windows 8's new interface. According to Microsoft, there were about 535,000 downloads of the developer preview within the first 12 hours of its release. Originally set to expire on March 11, 2012, in February 2012 the Developer Preview's expiry date was changed to January 15, 2013. Milestone 1, Build 7850, was leaked on April 12, 2011. It was the first build where the text of a window was written centered instead of aligned to the left. It was also probably the first appearance of the Metro-style font, and its wallpaper had the text shhh... let's not leak our hard work. However, its detailed build number reveals that the build was created on September 22, 2010. Its OS version read as 'Windows 7 Enterprise'. Milestone 2, Build 7955, was leaked on April 25, 2011. The traditional BSOD (Blue Screen of Death) was replaced by a new Black screen, although this was scrapped later. This build introduced a new Ribbon UI in Windows Explorer. Build 7959, with minor changes but the first 64-bit version, was released on May 1, 2011. On June 17, 2011, build 7989 was leaked. It introduced a new boot screen featuring the same fish as the default Windows 7 Beta wallpaper, which was later scrapped, and the circling dots as featured in the final. It also had the text Welcome below them, although this was also scrapped. The new File Explorer interface with "Ribbon" in Windows 8 On 29 February 2012, Microsoft released Windows 8 Consumer Preview, the beta version of Windows 8, build 8250. For the first time since Windows 95, the Start button is no longer present on the taskbar, though the Start screen is still triggered by clicking the bottom-left corner of the screen and by clicking Start on the Charm bar. Windows president Steven Sinofsky said more than 100,000 changes had been made since the developer version went public. The day after its release, Windows 8 Consumer Preview had been downloaded over one million times. Like the Developer Preview, the Consumer Preview is set to expire on 15 January 2013. Many other builds were released until the Japan's Developers Day conference, when Steven Sinofsky announced that Windows 8 Release Preview (build 8400) would be released during the first week of June. On 28 May 2012, Windows 8 Release Preview (Standard Simplified Chinese x64 edition, not China-specific version, build 8400) was leaked online on various Chinese and BitTorrent websites. On 31 May 2012, Windows 8 Release Preview was released to the public by Microsoft Major items in the Release Preview included the addition of Sports, Travel, and News apps, along with an integrated version of Flash Player in Internet Explorer. Like the Developer Preview and the Consumer Preview, the release preview is set to expire on January 15, 2013. On 1 August 2012, Windows 8 (build 9200) was released to manufacturing with the build number 6.2.9200.16384 . Microsoft planned to hold a launch event on 25 October 2012 and release Windows 8 for general availability on the next day. However, only a day after its release to manufacturing, a copy of the final version of Windows 8 Enterprise N (produced for European markets) leaked to the web, and several days later there were Pro and Enterprise leaks both IA-32 and x64. On August 15, 2012, Windows 8 was made available to download for MSDN and TechNet subscribers. Windows 8 was made available to Software Assurance customers on 16 August 2012. Windows 8 was made available for students with a DreamSpark Premium subscription on 22 August 2012, earlier than advertised. 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-colored theme, and the addition of new background options for the Start screen, lock screen, and desktop. Prior its to general availability on 26 October 2012, updates were released for some of Windows 8's bundled apps, and a "General Availability Cumulative Update" (which included fixes to improve performance, compatibility, and battery life) was released on Tuesday, 9 October 2012. Microsoft indicated that due to improvements to its testing infrastructure, general improvements of this nature will 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 2012, starting with its first television advertisement premiering on 14 October 2012. Microsoft's advertising budget for the operating system is US$1.5–1.8 billion, making Windows 8 the industry's biggest product launch in history.
