Ability to deploy Preview updates
There should be an option to install Preview updates, such as KB4338831 (July 18, 2018 Preview of Monthly Rollup) which fixes critical issues in KB4338815 (the regular July 2018 Monthly Rollup).
Right now (end of July 2018), after we update our machines using Update Management, we still need to install KB4338831 manually on each machine to keep important network services from locking up.

OK, it seems I was mistaken and the Preview updates are already being offered at least on some machines. In that case, I would very much like to have the ability to _skip_ Preview updates by default on production machines.
