Why can C++/WinRT run on Windows 7 now?
问题
根据这个问题，c++/winrt 不支持 Windows 7，因为 Windows 7 没有 WinRT；但是这个项目可以在 Windows 7 上运行，发生了什么？Windows 7 有了 WinRT 吗？WinRT 部署到了 Windows 7 上吗？
需要知道为什么现在 c++/winrt 可以在 Windows 7 上运行，谢谢。
英文:
"according to this question,c++/winrt doesn't support win7, because win7 got no winrt; but this project can run on win7, what happendd? win7 got winrt? winrt deployed to win7?"
need to known why c++/winrt can run on win7 now, thanks

"WinRT" 如在您链接的第一篇帖子中提到的是“Windows Runtime”的常用缩写。在Windows 7上不支持任何“Windows Runtime”样式的API。需要Windows 8或更高版本才能找到对任何“Windows Runtime” API 的支持。
在Windows 8早期，"Windows on ARM" 操作系统被称为 "Windows RT"，有时人们将其缩写为 "WinRT"，这增加了混淆。
"C++/WinRT 语言投影" 是一种使用 "Windows Runtime" API 的方式，也可以用于COM API。Kenny的项目演示了如何在运行在Windows 10上并在Windows 7上向下级运行的二进制中使用C++/WinRT。然而，"Windows Runtime" API 仍然不可用。只在Windows 7上使用COM。
英文:
"WinRT" as referenced in the first post you linked is a common short-hand for "Windows Runtime". There are no "Windows Runtime" style APIs supported on Windows 7. Windows 8 or later is required to find support for any "Windows Runtime" API.
> In the early days of Windows 8, the "Windows on ARM" OS was called "Windows RT" which people sometimes shortened to "WinRT" which just added to the confusion.
"C++/WinRT language projections" are a way to consume "Windows Runtime" APIs, and can also be used for COM APIs. Kenny's project demonstrates how you can use C++/WinRT in a binary that runs on Windows 10 and down-level on Windows 7. The "Windows Runtime" APIs are still not there. It's just using COM only on Windows 7.
