There are two types of computer groups and their queries.
One type is related to the settings of the OSIM parameters. "OSIM Computers" queries fill these groups.
The second type is for the software policies, and the groups are filled by membership of one or more "osim" group.
Example:
In OSIM you have a 64bit Win7 image, and you can choose if the computer is "office" or "production". Let's take "production" in this case.
The software policies send the specific software packages for Win7 64bit and production area.
We could setup a WebEx in case you want more details...
