Microsoft now stop rolling out the Windows 1809 (build 17763, Redstone 5) update due to the bug that deletes user data, then Windows will inform us by adding a new patch when the bug is fixed
Although Microsoft is about to release Creators update in the spring of 2017 with the ability to pause updates, it's still too late for users who suffered from automatically force update. Considering the awful year of Microsoft Windows 10 in 2016, we cannot give too much hope on the coming strategies, but we can stop Windows 10 update in registry
