Windows 10 introduces several new APIs and concepts (such as API contracts) that are not available on Windows 8.1. An app that relies on such new APIs and concepts cannot run on Windows 8.1. Additionally the app-model and a lot of packaging machinery for Windows 10 Universal apps is very different from Windows 8.1. Apps built with such new information cannot be successfully understood by Windows 8.1 for deployment. Also, Store will not make the Windows 10 apps available for download on Windows 8.1
Windows 10 引入了几个在 Windows 8.1 上不可用的新 API 和概念（例如 API 合同）。依赖于此类新 API 和概念的应用无法在 Windows 8.1 上运行。此外，Windows 10 通用应用程序的应用程序模型和许多打包机制与 Windows 8.1 大不相同。Windows 8.1 无法成功理解使用此类新信息构建的应用程序进行部署。此外，Store 不会在 Windows 8.1 上提供可供下载的 Windows 10 应用程序

A Universal Windows app is a Windows experience that is built upon the Universal Windows Platform (UWP), which was first introduced in Windows 8 as the Windows Runtime. Universal Windows apps are most often distributed via the Windows Store (but can also be side-loaded), and are most often packaged and distributed using the .APPX packaging format.
通用 Windows 应用是一种基于通用 Windows 平台 (UWP) 的 Windows 体验，该平台最初作为 Windows 运行时在 Windows 8 中引入。通用 Windows 应用程序最常通过 Windows 应用商店分发（但也可以旁加载），并且最常使用 .APPX 打包格式进行打包和分发。
"The best way to be ready for Windows 10 is to build your Universal Windows app for Windows 8.1 and Windows Phone 8.1 now."- Microsoft
