I need a way to tell if my workstations are licensed either with OEM, Volume/MAK or Retail licenses by building a PDQ query of some sort. I don't believe PDQ gives you this information in the built-in scanner. I know if it is in the registry I can scan for it. So far I've found a few different articles over where these keys are but they don't seem to be accurate.
This article: https://www.itninja.com/question/how-to-trace-windows-licenses-in-different-types-oem-open-license-full-pack-etc kind of states that you should be able to tell from the Pid string which type it is. I don't believe that to be correct though. When I check mine I get a 270 value which the article states is a Volume License. However when I run slmgr -dlv it states it's OEM. Does anyone know of a reliable way to get this information?
