Vista - Win32_Tpm class

I am trying to do some testing with WMI scripting of the TPM. There are a
few resources, but none with concrete code samples, and I am having a problem
with the scripts I've tried using the Win32_Tpm class. My instances of the
Win32_Tpm class are always null. Finally I broke down and simply tried to
find the class, and I cannot even do that. I used the following script:
======================================
strComputer = "."
strNamespace = "\root"

Set objSWbemServices = GetObject("winmgmts:\\" & strComputer & strNamespace)

Set colClasses = objSWbemServices.SubClassesOf()
For Each objClass in colClasses
Wscript.Echo objClass.Path_.Path
Next
======================================

I ran the script and piped it to -> findstr /I "Win32_Tpm" but nothing was
returned. It seems like the Win32_Tpm class is missing entirely, but that
can't be right can it? This is a fresh install of Windows Vista 64-bit (the
latest from the MSDN), I am logged into an account that is in the
Administrators group, and I am puzzled.

Thanks

Hi Dan, did you look at the "manage-bde.wsf" script? This uses the Win32_Tpm
class and is a good reference sample.
