Build 17666 of Windows 10 comes packing lots of new changes and features that are in testing with Insiders in the Fast and Skip Ahead rings right now. In fact, it's one of the more interesting builds we've received in a while, sporting things like Cloud Clipboard, dark mode in File Explorer and more.

As always, we've gone hands on with the new build to showcase all the noteworthy new changes you can find in build 17666, in case you're someone who doesn't want to install pre-release versions of Windows 10 onto your device for testing. The most notable changes in this build are improvements to Windows Sets, which now feature Acrylic, and Cloud Clipboard.

Also new in this build is dark mode for File Explorer, which also applies dark mode to the context menus on the desktop and in the File Explorer too (finally!) There are also UX improvements to Timeline and Windows Search, with Windows Search now offering a more clearer look at your recent Timeline activities.
