Insider preview for Microsoft HoloLens

  • Article
  • Applies to:
    HoloLens 2

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

This next update is on a newer codebase than what currently is available in the main builds. After you update a device to this build, your device won't update to our monthly releases until those releases catch up to the newer codebase. If necessary, you can still flash your device to go back to the general release.

Shared Microsoft Entra accounts

Using a shared Microsoft Entra account on your HoloLens results in the quickest login experience, since it does not require any credentials. This setup is ideal for scenarios where the following conditions are true:

  • Multiple people share the same set of HoloLens devices.
  • Access to Microsoft Entra resources, such as Dynamics 365 Guides content, is required.
  • Tracking who has used the device isn't required.

More details, including specific steps on how to configure these accounts, can be found in the Shared Microsoft Entra accounts in HoloLens article.

Tip

Validation Tip: Try this in your shared environments, utilizing your apps, to ensure that shared Microsoft Entra accounts work without any credentials.

Improve Intune app update experience

The Intune LOB App update does not enforce App shutdown if the App is still running on the device. Instead, the new version of the LOB App is installed and replaces the old App, once the old App is fully exited via user action, sign out or device reboot.

Refer to Consistent LOB App deployment and update for best practices on getting a consistent LOB App update experience for HoloLens devices.

Tip

Validation Tip: Try this in your own environment and utilizing your own app to ensure that your app doesn't shut down when an update is waiting to load.

Policy to enable auto-unlock

New policy to enable auto unlock MixedReality/AutoUnlock. When enabled, this policy allows a signed-in user to resume using the device without having to enter credentials.

Tip

Validation Tip: Try to modify this policy and ensure that auto unlock works in your specific environments and use cases.

Collect and view network connectivity report

Network connectivity report is added to Offline Diagnostics to help users investigate network connectivity issues on HoloLens 2 devices. After user triggers Offline Diagnostics, device IP addresses, Wi-Fi information, proxy settings and device’s connectivity to known cloud service endpoints are collected.

The report file NetworkConnectivityReport.txt will be included in the diagnostics ZIP file under Documents folder. Users can also view the report on device through Settings > Update & Security > Troubleshoot > View network connectivity report.

Tip

Validation Tip: If you use various network configurations, ensure it works with each configuration.

Enforce time sync during OOBE

During OOBE, the HoloLens device attempts to sync the device time with the time server after the device has connected to Wi-Fi.

Tip

Validation Tip: This will help you if you've flashed the build and then don't touch your device for a long time.

Update to eye tracking calibration

The option to perform eye tracking calibration is now shown on the device even if it has been deployed via Autopilot. Customers still have the option to disable this behavior via the existing MixedReality/SkipCalibrationDuringSetup policy.

Any user on the device can still choose to run eye calibration at any time to improve their experience.

Tip

Validation Tip: Try this on a shared device and ensure that eye tracking calibration occurs.

Policies to set device standby action

MixedReality/ConfigureDeviceStandbyAction and MixedReality/ConfigureDeviceStandbyActionTimeout policies enable configuring HoloLens 2 to execute certain action, when device is in modern standby after certain period of time. See policy documentation for supported actions.

Tip

Validation Tip: Modify these settings and ensure their functionality in your usage models and environments.

Fixes and improvements

  • Fixed an issue where the user picture displayed does not match the selected user on the sign in screen if MixedReality/PreferLogonAsOtherUser policy is enabled.

  • Fixed an issue where the user list cannot be dismissed by clicking on the "Add User" or the "Other User" buttons on the sign in screen if MixedReality/PreferLogonAsOtherUser policy is enabled.

  • Improved error handling when the device has reached the max number of supported users on device. See Remove users on a device for recommendations if your device is used by more than 63 Microsoft Entra accounts.

  • Improved error handling when the wrong user credentials are supplied when using web sign in.

  • Fixed an issue in Device Portal that would sometimes prevent the export of the spatial mapping database.

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:

Screenshot of the Windows Insider Channels explanation.

For more information, see Introducing Windows Insider Channels on Windows Blogs.

Prerequisites

These steps explain what to do before you sign up for Insider builds.

Update error 0x80070490 workaround

If you encounter update error 0x80070490 when updating on the Dev or Beta channel, try the following short-term workaround. It involves moving your Insider channel, picking up the update, and then moving your Insider channel back.

Stage one - Release Preview

  1. Select Settings > Update & Security > Windows Insider Program > Release Preview Channel.

  2. Select Settings > Update & Security > Windows Update > Check for updates.

  3. Accept any available update. After the update, continue to Stage two.

Stage two - Dev Channel

  1. Select Settings > Update & Security > Windows Insider Program > Dev Channel.

  2. Select Settings > Update & Security > Windows Update > Check for updates.

  3. Accept any available update.

FFU download and flash directions

  1. To test with a flight signed .ffu, flight unlock your device prior to flashing the flight signed FFU:

  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.
