Windows 8 需要一个支持物理地址扩展的处理器（尽管 32 位客户端版本无法充分利用它，因为 32 位操作系统的可用内存被人为限制在 4 GB 以内）、NX/XD 位和 SSE2 指令集。针对奔腾 D 系列处理器，Windows 8 要求处理器至少要有两个核心。它也是第一个支持基于 ARM 的处理器的 Windows 客户端版本（定名为 [[Windows RT]]）。 | Windows 8 需要一个支持物理地址扩展的处理器（尽管 32 位客户端版本无法充分利用它，因为 32 位操作系统的可用内存被人为限制在 4 GB 以内）、NX/XD 位和 SSE2 指令集。针对奔腾 D 系列处理器，Windows 8 要求处理器至少要有两个核心。它也是第一个支持基于 ARM 的处理器的 Windows 客户端版本（定名为 [[Windows RT]]）。 | ||
'''Windows 8''' is an operating system developed by Microsoft, which replaced [[Windows 7]] and was later succeeded by [[Windows 8.1]]. It was released to manufacturing on 1 August 2012 and was later made generally available on 26 October 2012. Intended as a direct response to [[w:Apple Inc.|Apple]]'s immediate success of the [[w:iPad|iPad]], Windows 8 sought to bring a complete overhaul to the familiar [[Windows]] user interface by introducing a full-screen tablet-oriented experience with increased emphasis on responsive touch input; most particularly, the addition of a [[Start screen]] and the introduction of the [[Windows Store]], a digital distribution platform for applications. Additional improvements such as the implementation of the [[w:USB 3.0|USB 3.0]] specification, [[w:UEFI#Classes|UEFI Class 3]] hardware support for 32- and 64-bit devices and improved startup times via hibernation snapshots were also added. | |||
The user-facing changes that Windows 8 brought were immediately controversial upon its release; the removal of the classic [[Start menu]] in favour of a full-screen interface and the Start button in place of a pop-out [[charms bar]] was subject to heavy criticism, forcing most desktop users to switch back to [[Windows 7]] or use third-party alternatives; it was commonly signified as one of the reasons behind its market failure. A [[Windows 8.1|subsequent update]] attempted to rectify some of the criticisms tied to Windows 8, but was unsuccessful in increasing adoption as trust had already eroded between Microsoft and its consumer base. | |||
It was one of the most short-lived releases of the Windows operating system family, with support ending on 12 January 2016; more than two years after the release of Windows 8.1. This is similar to the treatment of Service Packs by the Microsoft lifecycle policy, which allowed support for prior Service Packs to be dropped at least 24 months after the release of a successor. | |||
The operating system now requires a processor that supports the [[w:Physical Address Extension|Physical Address Extension]] (although 32-bit client editions cannot make full use of it due to being arbitrarily limited to 4 gigabytes of usable memory), the [[w:NX bit|NX/XD bit]] and the [[w:SSE2|SSE2]] instruction set. It also requires processors with at least 2 cores starting with the [[w:Pentium D|Pentium D]]. It is also the first client version of Windows to [[Windows on ARM|support ARM devices]] as a separate edition dubbed [[Windows RT]]. | |||
