Your Gateway to Windows Development

Windows SDK Documentation

Introduction to the Windows SDK

The Windows Software Development Kit (SDK) provides the headers, libraries, metadata, and tools necessary to develop applications for Windows. This documentation guides you through the various components of the SDK, helping you build powerful and innovative Windows experiences.

Whether you are developing classic desktop applications using Win32, modern Universal Windows Platform (UWP) apps, or leveraging the power of Component Object Model (COM), the Windows SDK is your essential toolkit.

Installing the Windows SDK

The Windows SDK is typically installed as part of Visual Studio. You can select the SDK components you need during the Visual Studio installation or modify your existing installation.

Alternatively, you can download the standalone SDK installers from the Windows SDK download page.

For detailed installation instructions, refer to the SDK Installation Guide.

Getting Started

To begin developing, ensure you have the latest Windows SDK installed. You'll need a development environment such as Visual Studio. Here's a basic workflow:

  1. Create a New Project: In Visual Studio, create a new project for your desired application type (e.g., C++ Desktop Application, UWP App).
  2. Include Headers: Your project will automatically include the necessary SDK headers, or you can manually include them using `#include <windows.h>` for Win32 development.
  3. Link Libraries: The linker will automatically find the necessary SDK libraries based on your project configuration.
  4. Write Code: Start writing your application logic using the Windows APIs.

Explore the Code Samples for practical examples.

Core Windows APIs

The Windows SDK exposes a vast array of APIs to interact with the operating system:

Win32 API

The foundational API for Windows programming, offering comprehensive access to the operating system's features. It's the backbone of most desktop applications.

Key components include:

  • Window management
  • User interface controls
  • File I/O
  • Process and thread management
  • Graphics (GDI, DirectX)

Example of a simple Win32 function call:


#include <windows.h>
#include <iostream>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    MessageBox(NULL, TEXT("Hello, Windows!"), TEXT("Win32 Example"), MB_OK);
    return 0;
}

Component Object Model (COM)

COM is a binary standard for creating reusable software components that operate within a client/server architecture. It's fundamental for many Windows subsystems.

Learn more about COM programming.

Universal Windows Platform (UWP)

UWP provides a modern, unified API model for building apps that can run across all Windows 10 and Windows 11 devices, from desktops to Xbox.

Key features include:

  • XAML for UI design
  • Modern controls and layouts
  • Sandboxed security model
  • App lifecycle management

Resources for UWP development can be found in the UWP Development Guide.

Windows Runtime (WinRT)

WinRT is the modern programming interface for Windows, providing language and ecosystem neutrality. It's the foundation for UWP apps and accessible from languages like C++, C#, and JavaScript.

Explore WinRT APIs.

Windows SDK Tools

The SDK includes essential tools for development:

  • Compilers and Linkers: For building your applications.
  • Debuggers: For identifying and fixing issues.
  • Diagnostic Tools: For performance analysis and system monitoring.
  • Manifest Tools: For managing application manifests.

Refer to the SDK Tools Reference for detailed information on each tool.

Understanding SDK Versions

Microsoft releases new versions of the Windows SDK with each major Windows update. Each SDK version targets a specific Windows version and may introduce new APIs, features, or improvements.

It's crucial to target an appropriate SDK version for your application to ensure compatibility and access to the latest platform capabilities.

Troubleshooting Common Issues

Encountering problems? Here are some common issues and their resolutions:

  • Missing Headers/Libraries: Ensure the correct SDK version is selected in your project settings and that the SDK was fully installed.
  • Compiler/Linker Errors: Verify your code syntax and ensure all dependencies are correctly linked. Consult the Compiler Error Index.
  • Runtime Crashes: Utilize the debugger to step through your code and identify the source of the crash.
