Try it out before you deploy it on a system you rely on
Other people are doing that for us all, which is why nobody with any sense will install it on a system they rely on (or "use" as I prefer to say).
I like how on every one of these Win 10 update horror story threads, there's always one "well I installed it and everything works for me" post, as if that somehow negates the actual disastrous consequences being described in the article.
