Windows Update错误代码0x80240439和Web服务xml错误

我正在运行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，而没有任何其他详细信息。事实证明，当我尝试安装任何应用程序时（在之前的某个时间确实可以正常工作），都会出现该错误。

我试图进行调查并在Windows Update日志中找到了这一点（抱歉，几行是德语的，但要点应该是可以理解的）：

前几行听起来像来自Web服务的XML响应无效。怎么会这样 我怀疑Microsoft服务器返回的数据不正确，所以可能是我的设备上有东西吗？
