Windows SDK and emulator archive

This archive contains SDK releases and updates for earlier Windows and Windows Phone platform versions, as well as emulator releases supporting development and UX testing for mobile device experiences.

For the latest editions of Visual Studio and the Windows 10 developer tools, see Downloads and tools for Windows.

Windows 10, version 21H1 is a scoped set of features for select performance improvements and quality enhancements. Developers should be aware of this release, but no action is necessary at this time.

A new Windows SDK will not be issued to accompany this version of Windows because this release doesn’t introduce new APIs. That means there’s no need to modify your project files or target a new version of Windows, and you should continue to use the Windows 10 SDK for Windows 10, version 2004. When setting the target version for your Windows app, Windows 10 build 19041 is still the most recent target version.
