Testing WMI for TPM chip

Question

Win 7 Ts with a group to pre-provision Bitlocker (SCCM 2012 SP1)
The group has a condition to run only if "select * from win32_TPM where IsEnabled Initialvalue="False"
This works fine on HP laptops but testing a Dell Latitude it skips past
Check wbemtest on the laptop I see the class with a value of <null>
so I 've added an extra condition if any of the conditions are true to include initialvalue="<null>"
still skips past the group - I also tried just "null" bit same again
any thoughts ?

Thanks for replying Niall. Yes I'm following your article and it works great. It is simply the TS test I need to determine whether to run or skip the "pre-provision Bitlocker" group.
My current test for the group is to test for Win32_tpm where isenabledinitialvalue="false". There is a mix of HP and Dell kit (all bare-metal out of box builds). For HP kit this test works fine i.e. the group runs but for Dell kit it skips the group therefore
evaluating the condition to be false - that's what I need to sort out. When you look in Bios the chip is there but TPM is not enabled or activated hence the steps using the CCTK (or HP Repset) but its just getting the right condition test so that it will run
the group correctly
