I'm having issue of Windows 10 client systems which are still running on build version 10240. Whereas previously I've tested one update which I've pushed on my system (KB3118754), which updated my system to 1511. However later, I've also pushed the same update to all computers via WSUS 2008 R2 but it showed the expired update. Now my computer running on latest build called 1703 whereas other client computers are still on 10240 version. Could you please help me on this? How can I update all client Windows 10 systems to latest build via WSUS server? Is there any particular cumulative update needed which I need to push through WSUS? Please help me to fix this issue.
