Support at Windows Community sorted out the problem for me earlier. Turned out was because the Windows Updates service is missing. The problem was resolved by doing in place upgrade using the Media Creation Tool. Now the updates are working as that should and I'm on Windows 10 version 1809, build 17763.316.
