Here are some things to try if your HoloLens is unresponsive, isn’t running well, or is experiencing software or update problems.
Restart your HoloLens
If your HoloLens isn’t running well or is unresponsive, try the following things.
First, try restarting the device: say, "Hey Cortana, restart the device."
If you’re still having problems, press the power button for 4 seconds, until all of the battery indicators fade out. Wait 1 minute, then press the power button again to turn on the device.
If neither of those things works, force restart the device. Hold down the power button for 10 seconds. Release it and wait 30 seconds, then press the power button again to turn on the device.
Reset or recover your HoloLens
If restarting your HoloLens doesn’t help, another option is to reset it. If resetting it doesn’t fix the problem, the Windows Device Recovery Tool can help you recover your device.
Resetting or recovering your HoloLens will erase all of your personal data, including apps, games, photos, and settings. You won’t be able to restore a backup once the reset is complete.
Resetting your HoloLens keeps the version of the Windows Holographic software that’s installed on it and returns everything else to factory settings.
To reset your HoloLens, go to Settings > Update > Reset and select Reset device. The battery will need to have at least 40 percent charge left to reset.
Recover using the Windows Device Recovery Tool
Before you use this tool, see if restarting or resetting your HoloLens fixes the problem. The recovery process may take some time, and the latest version of the Windows Holographic software approved for your HoloLens will be installed.
To use the tool, you’ll need a computer running Windows 10 or later, with at least 4 GB of free storage space.
To recover your HoloLens
