Microsoft first unveiled its Fluent Design language earlier this year, promising subtle changes to the company’s software in the future. The first part of Fluent Design will appear in the Windows 10 Fall Creators Update release tomorrow, but Microsoft is preparing more in the coming months. Most of the existing changes include subtle additions like blur effects, which is a type of design we saw back with Windows Vista.

All of the new design changes to Windows 10 are demonstrated in a new video from Microsoft. It’s a good showcase of how subtle the changes are, but it doesn’t tease much for the future. Microsoft’s Fluent Design System is designed to be the true successor to Microsoft's Metro design, and will appear across apps and services on Windows, iOS, and Android. Microsoft is focusing on light, depth, motion, material, and scale for its Fluent Design, with animations that make the design feel like it's moving during interactions in Windows.

We’re expecting to see even more changes in the next Windows 10 update, which is currently codenamed Redstone 4. Microsoft has started testing the initial features for this update, which is expected to arrive in March. The biggest addition so far is a new Cortana Collections feature, which will see and remember your browsing habits. As Microsoft progresses its testing, we’ll see more features added, alongside the return of the Timeline feature to improve resuming apps across Windows PCs and iOS or Android.
