The Anniversary Update introduces new features such as the Windows Ink platform, which eases the ability to add stylus input support to Universal Windows Platform apps and provides a new 'Ink Workspace' area with links to pen-oriented apps and features, enhancements to Cortana's proactive functionality, a dark user interface theme mode, a new version of Skype designed to work with the Universal Windows Platform, improvements to Universal Windows Platform intended for video games, and offline scanning using Windows Defender. While both were originally to be released in 2016, the second was moved into 2017 so that it would be released in concert with that year's wave of Microsoft first-party devices. The Anniversary Update was originally thought to have been set aside for two feature updates. This version was released on August 2, 2016, a little over one year after the first stable release of Windows 10.

It was codenamed ' Redstone 1' ( RS1) during development. The third stable build of Windows 10 is called version 1607, known as the Anniversary Update.
