WQL query where reg key is not present

Recommended Posts


Our hardware inventory is extended to capture some registry values that contain company specific tags.

However, on one of our images a value was missed (not present).

I need to create a collection containing these machines, but I’m struggling to work out how to do this in WQL.

Is it actually possible to use WQL to check if something does not exist (as opposed to being NULL)?


Our environment is SCCM 2012 SP1 CU3.

Thanks in advance.

Thanks for posting.


However, I'm struggling to understand how this will work in our scenario:


Registry key: HKLM\SOFTWARE\OurCompanyName

Value: BuildVersion (REG_SZ)

Data: BuildVersionTag (REG_SZ)


The query-based collection I need to create is to be populated by machines which do have the above registry key, but the BuildVersion value and BuildVersionTag data are not present at all.
