重新安装Microsoft Visual C++ Redistributable包，或者使用系统文件检查器修复系统缺失的文件。同时，也可以考虑下载并安装当前操作系统版本对应的DLL文件，并将其放置于系统路径下进行解决。下面是C++代码示例：

#include 
#include 

int main()
{
    HMODULE winrtString = LoadLibrary("api-ms-win-core-winrt-string-l1-1-0.dll");
    if (winrtString == NULL)
    {
        std::cout << "Failed to load library: api-ms-win-core-winrt-string-l1-1-0.dll" << std::endl;
        return 1;
    }
    else
    {
        std::cout << "Library loaded successfully." << std::endl;
        FreeLibrary(winrtString);
        return 0;
    }
}
