WMI access to registry

I'm having a lot of trouble figuring out how to use WMI to access the Windows
Registry. The only command I can see that does it is something like this...
(get-wmiobject StdRegProv -namespace
"root/default").Enumkey("HKEY_Local_machine", "Software/Microsoft", $regobj)
But this command returns the following error:
You cannot call a method on a null-valued expression.
At line:1 char:61
+ (get-wmiobject stdregprov -namespace "root/default").EnumKey( <<<<
"HKEY_LOCAL_MACHINE", "software\microsoft", $regobj)
Any ideas?

I am not sure about using the get-wmiobject cmdlet, but you can use [WMICLASS]/ManagementClass as shown below:

[long]$HKLM = 2147483650
$c = [WMICLASS]"root\default:stdregprov"
$g = $c.enumkey($HKLM,"software\microsoft")
$g | % { $_.sNames }

Even easier... use the builtin Powershell Provider to navigate the registry of a local PC:

PS HKLM:\> cd HKLM:\software\microsoft
PS HKLM:\software\microsoft> ls


Hive: Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\software\microsoft

SKC VC Name Property
--- -- ---- --------

3 0 AD7Metrics {}
1 0 ADs {}
