Microsoft has pushed out a new preview build of Windows 10 – actually, there are two fresh builds, but with no real differences between them – which makes a major change in terms of trying to avoid Windows updates happening when you don’t want them to by using clever machine learning tech.

But first off, you might be wondering why two builds have been released. Well, one of them is build 17723 which is for the next Redstone 5 update due later this year, and that’s going to fast ring denizens. The other is build 18204, which is for the following update due to land in the first half of 2019, and this is winging its way to ‘skip ahead’ testers.
