My internet connection is my phone - my laptop connects via its hotspot.
I have allowed Windows to download updates over metered connections and updates are not paused.
It says "Updates are available but they are too big to download over your current connection.". The update in question was KB5004237 - 2021-07 Cumulative Update for Windows 10 Version 2004 for x64-based Systems, but I expect the problem is not restricted to just one.
Under advanced options I have tried flicking the switch to allow updates on metered connections back and forth, pausing, unpausing and I have tried restarting. Same result. Does anybody know how I can persuade Windows to download updates or even do that manually?
