Wsus query needed - get WSUS-Computers, belonging WSUS-Group and Not Installed Count

Question

Hi,
i try to find a way by using basic WSUS powershell cmds in combination with piping in Server 2012 R2 to get all registered computers in WSUS plus belonging WSUS-Group and Update "Not Installed Count" as output.
Is that possible?
I tried multiple times and enden up in using posh - is there no way based on standard powershell commandlets.
Thank you
Peter

Hi Michael,
it seems that you are right :(. I tried out a few things with powershell (source
http://blogs.technet.com/b/heyscriptingguy/archive/2012/01/19/use-powershell-to-find-missing-updates-on-wsus-client-computers.aspx) - big problem is that i actually cant get belonging WSUS Group to Server object. I only are able to get all WSUS Groups
but cant find the right sytax to get only belonging ones.
Any ideas?
Thanks
Peter
