The release, which offers the most current build of the ever-growing Creators Update that was revealed in late-2016, was announced in a post over on the official Windows blog and brings with it a whole host of new features, changes to existing features, and fixes. In fact, the post announcing exactly what has changed as part of this particular preview release is a very lengthy one indeed, so this new update is one that those who have access to it will want to download soon. You will, without doubt, come across something new once you do.
