Get users with no primary device in SCCM

After a SCCM client agent implementation, it could be useful to see if there is any user, without any Primary User device.
This information could indicate if there is any computers in your domain, where the installation has been unsuccessful.

The devices that possibly hasn’t got the installation through Client Push, could be caught by using this setup. Another option would be to call the user to investigate further and install the client manually.

This code requires the Configuration Manager module.
