SBS 2011 Standard - not using WSUS (using GFI max). What do I need / want to do?

I am using GFI Max to keep machines patched.  But WSUS is installed (and running?) by default being this is an SBS 2011 Standard machine?

At least some of the machines say they are up to date when you run windows update but the screen says the last update was in early 2014 (these are win 7 pro machines) and it says 'your receive updates: managed by your system administrator.

Loads of pages on the web about how to turn off / disable / exempt all machiens from WSUS.  None all that new and many different ways are described with people debating what is the 'right' way and which will cause problems.  Haven't gotten a feeling that there's a consensus.

So what would you do on an SBS 2011 standard box if you were not using WSUS because you are using GFI max (or some other non-Microsoft RMM tool)  to keep the server and desktops patched?
