Windows 8.1 ISO
Windows 8.1 ISO (codenamed Blue) is an upgrade for Windows 8, a computer operating system released by Microsoft. First unveiled and released as a public beta in June 2013, it was released to manufacturing on August 27, 2013, and reached general availability on October 17, 2013, almost a year after the retail release of its predecessor. Windows 8.1 is available free of charge for retail copies of Windows 8 and Windows RT users via the Windows Store. Unlike service packs on previous versions of Windows, users who obtained Windows 8 outside of retail copies or pre-loaded installations (i.e., volume licensing) must obtain Windows 8.1 through new installation media from their respective subscription or enterprise channel. Microsoft’s support lifecycle policy treats Windows 8.1 similar to previous service packs of Windows: It is part of Windows 8’s support lifecycle, and installing Windows 8.1 is required to maintain access to support and Windows updates after January 12, 2016. However, unlike previous service packs, Windows 8.1 cannot be acquired via Windows Update.
Based on the official Microsoft lifecycle fact sheet this is the planned lifecycle for Microsoft Windows 8.1 ISO:
|Client operating systems||Latest update or service pack||End of mainstream support||End of extended support|
|Windows 8||Windows 8.1||January 9, 2018||January 10, 2023|
Released as part of a shift by Microsoft towards regular yearly major updates for its software platforms and services, Windows 8.1 aims to address complaints of Windows 8 users and reviewers on launch. Visible enhancements include an improved Start screen, additional snap views, additional bundled apps, tighter OneDrive (formerly SkyDrive) integration, Internet Explorer 11, a Bing-powered unified search system, restoration of a visible Start button on the taskbar, and the ability to restore the previous behavior of opening the user’s desktop on login instead of the Start screen. Windows 8.1 also added support for such emerging technologies as high-resolution displays, 3D printing, Wi-Fi Direct, and Miracast streaming.
