Windows 10 Insider Preview and Windows 10 Mobile Insider Preview

Installing Insider Preview builds is a great way to explore new Windows features, provide feedback and help shape future releases. Just remember: like any pre-release software, you may encounter bugs and other issues along the way. For this reason, Preview builds are made for people who know their way around a PC and don’t mind frequent updates with significant changes. But don’t worry. You actually have a choice of Insider Preview versions. If you’re not comfortable with the early "Fast Ring" versions, you can always select the Slow Ring or Release Preview - which are released later, but are more stable.

To install the Windows 10 Insider Preview, you’ll need to be running Windows 10.
