I'm rather liking the Windows 10 Creator's Edition Fall Update Feature Release 1709 for x64 based Systems (KB4041994).
It's full of little changes that just make everything that bit better. Like the way that the Onedrive sync status is now showed in a separate column, rather than on top of the file icon so that I couldn't tell what type of document I was looking at.
On tip though, after the upgrade I was a bit worried that my system disk had suddenly got a lot smaller. I managed to free off 41 GBytes just by deleting previous Windows installations.
