Getting registry value using WMI

Question

I\'m getting an exception which I can\'t find documented anywhere. Here is the exception:

The following exception occurred while retrieving the type name hierarc         


        

Answer 1

don't you over complicate things ? all of these to read a value from registry ? what about someting like that

icm -ComputerName $endpoint -ScriptBlock {Get-ItemProperty HKLM:\software\7-zip\ |select path} 

Answer 2

Either method works, but using the measure-command I found the example that icm was 10 times slower, 0.47 seconds versus 4.8 seconds using ICM.

Answer 3

If you must use WMI use something like this (taken from the Scripting Guy blog):

$endpoint = 'someEndpointName'

$basekey  = [uint32]'0x80000002'
$subkey   = 'SOFTWARE\Company\EOS Version'
$value    = 'Build S Version'

$reg = [wmiclass]"\\$endpoint\root\default:StdRegProv"
$buildSVersion = $reg.GetStringValue($basekey, $subkey, $value).sValue

Personally I'd prefer using remote registry access, though:

$endpoint = 'someEndpointName'

$basekey  = 'LocalMachine'
$subkey   = 'SOFTWARE\Company\EOS Version'
$value    = 'Build S Version'

$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($basekey, $endpoint)
$key = $reg.OpenSubKey($subkey, $true)
$buildSVersion = $key.GetValue($value)
