#PSTip Access remote registry using PowerShell
Using the Microsoft.Win32.Registry class it is possible to access both–the local registry and, more importantly, the registry of a remote system. Using the PowerShell cmdlet this is unfortunately not possible. Ravikanth posted a similar tip in PowerShell Magazine in which he uses it to retrieve SQL instance names using remote registry.
The following code will retrieve a list of sub keys from the HKLM:\Software path in the registry on Server1 computer:
$Reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine,Server1) $RegSubKey = $Reg.OpenSubKey("System\CurrentControlSet") $Values = $RegSubKey.GetSubKeyNames()
Using this information it is possible to extract a value from the subkey as well. The following code sample will extract the path parameter from the first subkey in the Software container.
$RegPath = Join-Path 'Software' $Values $Reg.OpenSubKey($RegPath).GetValue('Path')
