I am still on my win10 1803 and yeah it cannot update even if it wants to. I feel this build is probably smooth and less buggier than the new one as I have no issues with it running even emulators so far. also running VMware with good old win xp sp3 32bit on it to play some old games tht I used to play on win xp until 8, 8.1 destroyed its compatibility.
BTW Stopping the updates from d'loading is very simple just open group policy editor.
and in tht editor head to Computer Configuration>Administrative Templates>Windows Components>Windows Update.
select Configure Automatic updates option, and in the new window tht opens, set it to disabled option from the not configured option.
Now apply it, ok and then close the group policy editor. Head to services.msc by either typing it in the run dialog box or in the search box of windows, stop the windows update service from running and set it to disabled, apply it and close.
open the uwp setting app and set it to defer updates the security and the feature updates. Thts it. u have finally disabled the windows updates from working and downloading stuff.
Also this wont affect the uwp store apps in any way and u can still d'load and use apps from store too.
Reverse this steps if u want to get the win 10 updates working like before.
This step should work for win 10 pro and other editons of windows except for home
