On March 26, 2013, Microsoft officially acknowledged Windows "Blue", the internal codename for an update to Windows 8. On May 14, Microsoft officially announced that the "Blue" update would be named Windows 8.1 On June 26, 2013, a public preview of the 8.1 update was released; it is obtained through either Windows Store (following the installation of a special update that adds the ability to download the preview) and as a full ISO image of Windows 8 Pro with the 8.1 update installed on Microsoft's downloads portal. The Enterprise version was made available shortly afterwards on July 30, 2013. On August 14, 2013, Microsoft reported Windows 8.1 would be available on October 18, 2013. Microsoft announced on August 27, 2013 that it had released Windows 8.1 to OEM hardware partners in preparation for its release. Unlike past releases and service packs for Windows, where MSDN Plus and TechNet Plus subscribers as well as volume licensees were able to obtain the RTM version prior to launch, Windows 8.1 will not be officially released to anyone else until its official launch. In response to the change in practice, a spokesperson stated that it would allow Microsoft to work with OEMs "to ensure a quality experience at general availability." However, after criticism, Microsoft reversed its decision and released the RTM build on MSDN and TechNet on September 9, 2013. Changes Microsoft indicated that the 8.1 update would change "key aspects" of the operating system, addressing the criticism that Windows 8 faced from users and reviewers on launch.The update contains a number of improvements throughout the operating system, but primarily focuses on improving functionality within the "Metro" shell and Windows Store apps, expanding search capabilities, adding support for more emerging technologies, and features intended to improve the usability of the desktop interface following the changes that were made to it on Windows 8 (such as restoring a visible Start button, the ability to disable hot corners, and the ability to skip the Start screen when logging in). System requirements According to Microsoft, the system requirements for Windows 8.1 are the same as Windows 8; however, x64 variants of Windows 8.1 require CPUs that support four specific x86 instructions: PrefetchW, CMPXCHG16b, LAHF and SAHF. In addition, Windows 8.1 Preview does not work on some newer Intel Atom-based devices. Microsoft has also set new requirements for device manufacturers willing to obtain Microsoft device certification. These requirements are expected to become effective in 2014 and 2015.
