XAML 设计器未加载

我正在尝试开发适用于 Windows 10 的通用应用程序，但 XAML 设计器无法加载。我尝试重新安装 Visual Studio，但似乎没有任何效果。

Error:

System.Runtime.InteropServices.COMException
该应用程序没有启动。 （HRESULT 异常：0x8027025B）

有类似的问题。使用 VS 2015 Enterprise 和 Win8.1 x64。已经这样解决了：

1. 启动防火墙服务（已关闭）

2. 将 UAC 更改为推荐级别（已关闭）

3. 以 Microsoft 用户帐户登录（我想，这将是至关重要的）

4. 启动Windows应用商店应用程序（已阅读这是所有问题的根源）

5. 开始VS。这位设计师开始工作后

6. 重新启动系统，恢复所有设置，包括。防火墙和UAC 最后，即使 MS 用户帐户被禁用，设计器也可以在任何用户下正常工作。
