Welcome to the latest Insider Preview builds for HoloLens! Get started and provide valuable feedback on HoloLens for our next major operating system update.

Tip

Organizations that have moved, or are moving toward, production deployment at scale should keep a subset of test devices on Insider builds to validate new features and builds.

Windows Insider release notes

Looking for a new feature but don't see it? We released many new features as part of the main builds. Check out the release notes if you think a feature might be missing.

Note

Only devices in the Dev channel receive these Insider build features.

Important

The November 2024 update has all the latest features and fixes for HoloLens 2. We are not currently flighting any new features. New features or fixes may be flighted in the future.

Start receiving Insider builds

This section explains the steps to prepare devices and then the steps to receive Insider builds.

Tip

Once you enroll a device into Insider builds, we strongly recommend that your organization keeps a set of test devices enrolled, too. With a set of test devices, your organization can validate builds more easily as they come out. Timely and efficient validation creates an easier experience and helps if your normal production devices are blocked from Insider builds.

Note

Windows Insider is moving to Channels. The Fast ring will become the Dev Channel, the Slow ring will become the Beta Channel, and the Release Preview ring will become the Release Preview Channel. Here’s how that mapping looks:

  2. Flash FFU. Now you can flash the flight signed FFU using ARC.

Provide feedback and report issues

Use the Feedback Hub app on your HoloLens to provide feedback and report issues. Feedback Hub helps you include the necessary diagnostics information to help our engineers quickly debug and resolve any problem. Report issues with the Chinese and Japanese versions of HoloLens the same way.

Note

Be sure to select Yes when a prompt asks whether you'd like Feedback Hub to access your documents folder.

Note for developers

You're welcome and encouraged to try developing your applications using Insider builds of HoloLens. Check out the HoloLens Developer Documentation to get started. Those instructions also work with Insider builds for HoloLens. Use the same builds for Unity and Visual Studio that you're already using for HoloLens development.

Stop receiving Insider builds

If you no longer want to receive Insider builds of Windows Holographic, you have two options:

  • Opt out on a HoloLens running a production build:

    1. Go to Settings > Update & Security > Windows Insider Program > Stop Insider builds.
    2. Follow the instructions to opt out your device.

  • Use the ARC to recover your device to a non-Insider version of Windows Holographic.

Caution

A known issue causes users who un-enroll from the Windows Insider program, and then manually install a fresh Insider preview build, to experience a blue screen. Afterward, the user must recover the device manually. Learn more about this Known Issue.

To verify that your HoloLens is running a production build:

  1. Locate the build number through Settings > System > About.
  2. Check the build number against the release notes for production build numbers.
