OpenRemoteBaseKey尝试执行未经授权的操作

Question

我正在学习Powershell，我正在在线关注此博客，该博客允许访问远程计算机上已安装的软件。同时跟随代码。我收到此错误，但我在网上找不到任何答案。希望有人可以提供帮助。我真的很感激。

Exception calling "OpenRemoteBaseKey" with "2" argument(s): "Attempted to perform an unauthorized operation."
At line:4 char:1
+ $regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($type, $Sr ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : UnauthorizedAccessException

You cannot call a method on a null-valued expression.
At line:5 char:1
+ $regKey.OpenSubKey($key)
+ ~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull

到目前为止，这是我的代码；

$srv = 'testpc01'
$key = "SOFTWARE\Microsoft\Windows\CurrentVersion"
$type = [Microsoft.Win32.RegistryHive]::LocalMachine
$regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($type, $Srv)
$regKey.OpenSubKey($key)

谢谢！
