从 Windows 7 Pro 到 8 Pro 执行就地升级后，我无法让 NuGet 的包管理器控制台在 Visual Studio 2012 Pro 中运行。我收到的错误是：
The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\WINDOWS\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(2977) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

The term 'Get-ExecutionPolicy' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
在过去的几天里，我一直在寻找解决此问题的方法，但一直空无一物。我已经尝试了所有这些都无济于事：
- 禁用所有 Visual Studio 附加组件
- 重置所有设置
- 重新安装 Visual Studio
- 修复 Visual Studio
- 在 Visual Studio 之前启动 PowerShell（这是否只是意味着启动 PowerShell，然后启动 Visual Studio？）
- 以管理员身份运行 PowerShell 和 Visual Studio
- 在安全模式下运行 Visual Studio
- 将 Power Shell ExecutionProperty 设置为不受限制
Visual Studio 一直表现出其他奇怪的行为，例如在尝试将 Click 事件添加到特定页面上的 XAML 时持续崩溃，因此我的直觉说这不是真正的 Power Shell 或 NuGet，而是我的 OS/Visual 的问题工作室。
除非有人有解决方案，否则我认为我只能对 Windows 8 进行全新安装并希望能够修复它。
