我运行的是 Windows 10 Pro，版本 1511（内部版本 10586.545）。我想安装 Xbox 配件应用程序，但收到错误代码 0x80240439，没有任何进一步的详细信息。事实证明，当我尝试安装任何应用程序时都会收到该错误（以前肯定在某个时候可以正常工作）。
我尝试进行调查并在 Windows 更新日志中发现了这一点（有几行是德文，抱歉，但大意应该是可以理解的）：

前几行听起来像是来自 Web 服务的 XML 响应无效。怎么会这样？我怀疑 Microsoft 服务器返回了错误的数据，所以可能是我的设备出了问题？
答案1
显然我的 Windows 更新以某种未知的方式被破坏了，无法更新到最新的 Windows 版本。按照 Ramhound 的建议，我通过运行可执行文件手动更新了http://go.microsoft.com/fwlink/?LinkID=799445，然后它就起作用了。
