Help co-create an even better Windows

Installing Insider Preview builds is a great way to explore new Windows features.

Windows 10 Insider Preview Builds

Insider Preview Builds are earlier releases of Windows that are made available exclusively to Windows Insiders before a public release.1 All you need is a PC running Windows 10 to get started.

Once you’ve have a chance to try an Insider build, provide our engineers feedback — simply visit the Feedback Hub app in your Start menu.

How to install the latest Insider Preview Build

If you’ve never installed a Preview Build:

  • On your PC with Windows 10 installed: Type "Windows Insider Program settings" in the search bar (lower left), then open to get Insider Preview Builds.2
If you've already installed a Preview Build:
  • On your PC: Go to Windows Update in Settings and click "Check for updates". If Windows Update says your device is up to date, you have the latest build.

Check out amazing new features

We're working on new Windows features all the time. With Insider Preview Builds, you get to be among the first to try these features before the general public. Here are just a few recent highlights:

  • Stay better connected with those closest to you: With My People, you can pin your favorite contacts directly to the taskbar and view multiple communication apps together, all filtered to each person on your taskbar.3 Contacts will display a counter if there are unseen messages.4 You can also drag-and-drop files directly onto the contacts in your taskbar to start an email, see emoji from your pinned contacts, and more.
  • Improve battery life with Power Throttling: Fill in PDF-based forms within Microsoft Edge, make notes directly on PDFs, navigate longer PDFs with the Table of Contents feature and even rotate documents for easier reading.5
  • Free up more storage space: In Storage Sense, you can choose to automatically delete files in your Downloads folder that haven’t been changed for 30 days.

Preview with confidence

No beta software is perfect. That's why we offer Insiders different versions of Insider Preview Builds. We call them Rings:

  • The Slow Ring is for most Insiders who simply want to explore new Preview features with minimal risk to their devices.
  • The Fast Ring receives Insider Preview Builds more often than the Slow Ring. It’s for advanced Insiders who want to explore new features even sooner — and don’t mind dealing with the bugs and other issues that come with these builds.
