Windows 8.1 is a version of Windows NT family of operating systems and an upgrade for Windows 8. 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 Windows Store. Unlike service packs on previous versions of Windows, users who obtained 8 outside of retail copies or per-loaded installations (i.e., volume licensing) must obtain 8.1 through new installation media from their respective subscription or enterprise channel. Microsoft's support life-cycle policy treats Windows 8.1 similar to previous service packs of Windows: It is part of Windows 8's support life-cycle, and installing 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 and only accepts 8.1-specific product keys.
