WSUS – Windows Server 2016

Hi one and all, So after many weeks of trying to figure out this issue of why my Windows 10 Clients aren’t picking up the updates from my WSUS, I have had no further luck. I have created all the membership groups for my place of work, I can see the updates in the updates section of the WSUS console, I can approve them and I can see them being downloaded where it starts XXXX MB of XXXX MB downloaded, yet when I click on Check for updates on my Win10 Client machines, it says I’m up to date. I’m really struggling on this one so any help whatsoever would be fantastic. Regards
