I am trying to create a collection in PDQ Inventory that will only include our Windows OS (7, 10, 2012r2, 2016, etc) and that do not have a certain software installed. I have the collection working with the criteria of the software not being installed but it is also pulling in our Macs, linux servers, and vmware hosts that are in AD. Short of moving these devices out of the scanned tree what is the best way to run the filters so that it will only display the Windows OS without this software installed? I have tried every way I can think of and it does not return only the ones I want. It keeps showing either ALL the devices regardless of OS or only those missing the software which includes the linux/mac/vmware/etc.
