At the Consumer Electronics Show in January 2011, it was announced that the next version of Windows would add support for ARM System-on-chips alongside the existing 32-bit processors produced by vendors, especially AMD and Intel.

Development Early development ĭevelopment started in 2009 while Microsoft was finishing work on Windows 7. As of August 2023, 0.35% of PCs are running Windows 8.

Mainstream support for the Embedded Standard edition of Windows 8 ended on July 10, 2018, and extended support ended on July 11, 2023. Support for RTM editions of Windows 8 ended on January 12, 2016, and with the exception of Windows Embedded 8 Standard users, all users are required to install the Windows 8.1 update. Windows 8 was ultimately succeeded by Windows 10 in July 2015. Microsoft released Windows 8.1 in October 2013, which addressed some aspects of Windows 8 that were criticized by reviewers and early adopters and also incorporated improvements to various aspects of the operating system. Despite these shortcomings, 60 million licenses were sold through January 2013, a number that included both upgrades and sales to OEMs for new PCs. Although the reaction to 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 confusing and unintuitive, especially when used with a keyboard and mouse instead of a touchscreen. Windows 8 received a mostly negative reception. No CPUs without PAE, SSE2 and NX are supported in this version. Windows 8 is the first version of Windows to support the ARM architecture under the Windows RT branding. Additional security features – including built-in antivirus software, integration with Microsoft SmartScreen phishing filtering, and support for Secure Boot on supported devices – were introduced. Windows 8 also added support for USB 3.0, Advanced Format, near-field communication, and cloud computing. Many of these features were adapted from Windows Phone. In particular, these changes included a touch-optimized Windows shell and start screen based on Microsoft's Metro design language, integration with online services, the Windows Store, and a new keyboard shortcut for screenshots. Windows 8 introduced major changes to the operating system's platform and user interface with the intention to improve its user experience on tablets, where Windows competed with mobile operating systems such as Android and iOS. Nearly three months after its initial release, Windows 8 finally made its first retail appearance on October 26, 2012. It was released to manufacturing on August 1, 2012, and was made available for download via MSDN and TechNet on August 15, 2012. Windows 8 is a major release of the Windows NT operating system developed by Microsoft.
