Windows App SDK
The Windows App SDK provides a unified set of APIs and tools that are decoupled from the OS and released to developers via NuGet packages. These APIs and tools can be used in a consistent way by any desktop app on Windows 11 and downlevel to Windows 10, version 1809.
You can get the Windows SDK in two ways: install it from this page by selecting the download link or by selecting “Windows 11 SDK (10.0.22621.0)” in the optional components of the Visual Studio 2022 Installer.
Before you install this SDK:

The Windows SDK has the following minimum system requirements:
Supported operating systems
- Windows 10 version 1507 or higher: Home, Professional, Education, and Enterprise (LTSB and S are not supported for UWP)
- Windows Server 2022, Windows Server 2019, Windows Server 2016, and Windows Server 2012 R2 (Command line only)
- Windows 8.1
- Windows 7 SP1
(Not all tools are supported on earlier operating systems)
- 1.6 GHz or faster processor
- 1 GB of RAM
- 4 GB of available hard disk space
Additional SDK requirements
Installation on Windows 8.1 and earlier operating systems requires an Update for Universal C Runtime in Windows. To install through Windows Update, make sure you install the latest recommended updates and patches from Microsoft Update before you install the Windows SDK.
Windows app samples are now available through GitHub. You can browse the code on GitHub, clone a personal copy of the repository from Git, or download a zipped archive of all the samples. We welcome feedback, so feel free to open an issue within the repository if you have a problem or question. These samples are designed to run on desktop, mobile, and future devices that support the Universal Windows Platform (UWP).
Previous SDK versions
Previously released SDKs and emulators, including update details, can be found on the archive page.
API Light Up
When you use new APIs, consider writing your app to be adaptive so that it runs correctly on the widest array of Windows devices. An adaptive app "lights up" with new features wherever the devices and Windows version supports them, but otherwise offers only the functionality available on the detected platform version. For implementation details, see the Version adaptive code article.
