Microsoft today released the first preview build of Windows 11 to those in the Dev Channel of the company’s Windows Insider program. If you have joined the Insider program and meet Microsoft’s new — and somewhat complicated — system requirements for the new operating system, you should see the update soon.

This first preview includes most of the new features Microsoft has promised for Windows 11, including the new look and feel, themes, widgets, the new snap layouts and the updated File Explorer. But there are also some features that didn’t yet make the cut for this first release. Support for Android apps and the new built-in Teams integration, for example, are coming in a later release, but a preview of the new Windows Store is already available today.
