I've been trying to extract some registry key values and failing miserably.

This is as far as I can get:-

$val = @()
$Val = Get-ChildItem "hklm:\SOFTWARE\NetApp\" | Where name -eq "HKEY_LOCAL_MACHINE\SOFTWARE\NetApp\HostUtilities"

Name                           Property 
----                           -------- 
HostUtilities                  Version      : 7.0.5208.722   
                               InstallDir   : C:\Program Files\NetApp\Windows Host Utilities\   
                               LogDir       : C:\temp\netapp\ 
                               Multipathing : 1
                               Protocols    : 3  

I can't figure out how to grab the individual values, like InstallDir. Thanks in advance!

I don't have any NetApp applications on my machine but this should help

Look at the PowerShell entries

PS> Get-ChildItem -Path 'HKLM:\SOFTWARE\Microsoft\PowerShell\3'


    Hive: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3


Name                           Property
----                           --------
0409                           Install : 1
PowerShellEngine               ApplicationBase         : C:\Windows\System32\WindowsPowerShell\v1.0
                               ConsoleHostAssemblyName : Microsoft.PowerShell.ConsoleHost, Version=3.0.0.0, Culture=neutral,
                               PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=msil
                               ConsoleHostModuleName   : C:\Windows\System32\WindowsPowerShell\v1.0\Microsoft.PowerShell.ConsoleHost.dll
                               PowerShellVersion       : 5.1.16299.15
                               PSCompatibleVersion     : 1.0, 2.0, 3.0, 4.0, 5.0, 5.1
                               PSPluginWkrModuleName   : C:\Windows\System32\WindowsPowerShell\v1.0\system.management.automation.dll
                               RuntimeVersion          : v4.0.30319

Under the PowerShellEngine you have a bunch of entries but if you use
Get-ChildItem -Path 'HKLM:\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine\'

You get nothing back. You can use get-ItemProperty

PS> Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine\' -Name PowerShellVersion


PowerShellVersion : 5.1.16299.15
PSPath            : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine\
PSParentPath      : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3
PSChildName       : PowerShellEngine
PSDrive           : HKLM
PSProvider        : Microsoft.PowerShell.Core\Registry

Thanks Richard. Get-ItemProperty is a solution.
Basic question following on from this is how to output the string value as opposed the @{...}.


$str = Invoke-command -computer "JUNO" { Get-ItemProperty -Path 'HKLM:\SOFTWARE\NetApp\HostUtilities'  -Name InstallDir } | Select InstallDir

$Str
#output...
@{InstallDir=C:\Program Files\NetApp\Windows Host Utilities\}

I've tried $Str.ToString() but that doesn't work.

It's ok, I forgot... use Select -ExpandProperty InstallDir.

Thanks Richard, I'm done. 🙂
