Question

我渴望找出哪些变量是受保护的或常量，我决定只看看哪些变量可以被删除 - 假设上面提到的那些将被遗漏。我没有意识到的是，这些变量的删除不仅限于ISE本届会议的范围 - 而且不仅仅是Powershell全球 - 而是全球系统。我希望有人能帮助我让ISE再次工作。

我的愚蠢：

Remove-Variable *

...导致报告了一堆错误，之后我执行dir variable:时只剩下少量（10-15）。认为这没什么大不了的，ISE的重新启动会使我恢复正常，我关闭它 - 它不会启动。

其他症状

我发现我已经丢失了环境变量%windir%之类的内容 - 这是最有趣的转折，阻止您打开高级系统设置（无法找到%windir%\system32\systempropertiesadvanced.exe ）设置你的ENV备份...（是的，我可以直接运行）

更新：我发现了一个额外的效果/症状：Windows报告说在自动更新无法正常工作后我可能没有正版Windows。我没有意识到像一些ENV变种那样简单的东西会消灭它。 HRM。

那么 - 有谁知道如何恢复或重新创建成功运行ISE所需的环境？

（是的，我尝试删除并重新添加功能，并重新启动。）

Answer 1

我刚刚在ISE中删除了 - 变量*，没有任何事情发生。我仍然可以打开ISE并像往常一样工作。我还做了一个-WhatIf来看看真正被删除的内容。

感谢大家的帮助 - 这就是我所做的，虽然我不确定是否让我100％回到任何地方，但我允许我使用ISE，Hyper-V管理器并再次验证为真品。

我转到另一个Server 2008 R2框，比较密钥并手动编辑注册表并将这些值添加回损坏的计算机：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
  Path=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;
  PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC
  PSModulePath=C:\Windows\system32\WindowsPowerShell\v1.0\Modules\
  TEMP=C:\Windows\TEMP
  TMP=C:\Windows\TEMP
  windir=C:\Windows

我倾向于提升ISE的管理员权限，因为它影响了会议的主要原因。

删除所有变量后，（愚蠢地）Powershell ISE无法启动
