**windows.h头文件的位置通常位于[Windows Kits](https://www.baidu.com/s?sa=re_dqa_generate&wd=Windows%20Kits&rsv_pq=826ce39d000a376b&oq=window%20sdk%20%E5%A4%B4%E6%96%87%E4%BB%B6%20windows.h%20%E5%9C%A8%E5%93%AA%E9%87%8C&rsv_t=0eccxBhreAvLKpb4c5Pz5pBO7Vlm7qSMlzSPgleqaZ0/Fn1oqhP66ugGx/iOBuVZt6o&tn=98010089_dg&ie=utf-8)的Include目录下。** 例如，在64位系统上，windows.h的位置可能为：

*   **Windows 7 SDK**：`C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include`
*   **Windows 8 SDK**：`C:\Program Files (x86)\Windows Kits\8.0\Include\um`
*   **Windows 8.1 SDK**：`C:\Program Files (x86)\Windows Kits\8.1\Include\um`
*   **Windows 10 SDK**：`C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\um`

这些路径可能会根据你安装的[Windows Kit](https://www.baidu.com/s?sa=re_dqa_generate&wd=Windows%20Kit&rsv_pq=826ce39d000a376b&oq=window%20sdk%20%E5%A4%B4%E6%96%87%E4%BB%B6%20windows.h%20%E5%9C%A8%E5%93%AA%E9%87%8C&rsv_t=0eccxBhreAvLKpb4c5Pz5pBO7Vlm7qSMlzSPgleqaZ0/Fn1oqhP66ugGx/iOBuVZt6o&tn=98010089_dg&ie=utf-8)版本有所不同。如果你在使用[Visual Studio](https://www.baidu.com/s?sa=re_dqa_generate&wd=Visual%20Studio&rsv_pq=826ce39d000a376b&oq=window%20sdk%20%E5%A4%B4%E6%96%87%E4%BB%B6%20windows.h%20%E5%9C%A8%E5%93%AA%E9%87%8C&rsv_t=0eccxBhreAvLKpb4c5Pz5pBO7Vlm7qSMlzSPgleqaZ0/Fn1oqhP66ugGx/iOBuVZt6o&tn=98010089_dg&ie=utf-8)时遇到找不到windows.h的问题，可以按照以下步骤解决：

1.  **检查[项目属性](https://www.baidu.com/s?sa=re_dqa_generate&wd=%E9%A1%B9%E7%9B%AE%E5%B1%9E%E6%80%A7&rsv_pq=826ce39d000a376b&oq=window%20sdk%20%E5%A4%B4%E6%96%87%E4%BB%B6%20windows.h%20%E5%9C%A8%E5%93%AA%E9%87%8C&rsv_t=0eccxBhreAvLKpb4c5Pz5pBO7Vlm7qSMlzSPgleqaZ0/Fn1oqhP66ugGx/iOBuVZt6o&tn=98010089_dg&ie=utf-8)**：右键点击项目 -> 属性 -> 配置属性 -> 常规，确保Windows SDK版本选择的是你已安装的版本。
2.  **调整包含目录**：在属性页的VC++目录 -> 包含目录中添加相应的路径，例如 `C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\um`。

通过以上步骤，你应该能够找到并正确引用windows.h头文件。
