There's plenty more beyond the web. The preview introduces a "lower blue light" option that, like F.lux or the night modes on some phones, will gradually shift colors to ease the strain on your eyes (and theoretically, help you sleep) when it gets dark. And did we mention that you can organize the Start menu's tiles into folders? It'll seem familiar if you've used Windows Phone or Windows 10 Mobile, but it's definitely welcome if you'd like to have a lot of app shortcuts.

Other improvements? You'll find a more app-centric sharing option with increased awareness of what you're running and what you like to use. Windows is also building in a selective screen capture mode that was previously limited to OneNote, a more formal introduction to Cortana for new users, an on-demand "refresh Windows" option to reinstall the OS and better support for very high resolution displays. If you're an Insider and are willing to live with the inevitable glitchiness of a preview, you'll definitely want to give this a peek.
