# Manage HoloLens updates
HoloLens uses Windows Update, just like other Windows 10 devices. When an update is available, it will be automatically downloaded and installed the next time your device is plugged in and connected to the internet. This article describes how to manage updates in an enterprise or other managed environment. For information about managing updates to individual HoloLens devices, see [Update HoloLens](hololens-update-hololens.md).
HoloLens uses Windows Update in the same manner as other Windows 10 devices. When an update is available, it is automatically downloaded and installed the next time that your device is plugged in and connected to the internet. This article describes how to manage updates in an enterprise or other managed environment. For information about managing updates to individual HoloLens devices, see [Update HoloLens](hololens-update-hololens.md).
## Manage updates automatically
Windows Holographic for Business can use [Windows Update for Business](https://docs.microsoft.com/windows/deployment/update/waas-manage-updates-wufb) to manage updates. All HoloLens 2 devices can use Windows Holographic for Business. Make sure that they use Windows Holographic for Business build 10.0.18362.1042 or a later build. If you have HoloLens (1st gen) devices, you have to [upgrade them to Windows Holographic for Business](hololens1-upgrade-enterprise.md) to manage their updates.
Windows Update for Business connects HoloLens devices directly to the Windows Update service. By using Windows Update for Business, you can control multiple aspects of the update process: which devices get which updates at what time. For example, you can roll out updates to a subset of devices for testing, then roll out updates to the remaining devices at a later date. Or you can define different update schedules for different types of updates.

> For HoloLens devices, You can automatically manage feature updates (released twice a year) and quality updates (released monthly or as needed, including critical security updates).

For more information about update types, see [Types of updates managed by Windows Update for Business](https://docs.microsoft.com/windows/deployment/update/waas-manage-updates-wufb).
You can configure Windows Update for Business settings for HoloLens by using policies in a Mobile Device Management (MDM) solution such as Microsoft Intune.
For a detailed discussion of how to use Intune to configure Windows Update for Business, see [Manage Windows 10 software updates in Intune](https://docs.microsoft.com/intune/protect/windows-update-for-business-configure).

> Intune provides two policy types for managing updates: *Windows 10 update ring* and *Windows 10 feature updates*. The Windows 10 feature update policy type is in public preview at this time and is not supported for HoloLens.

### Plan and configure update rollouts for HoloLens 2
HoloLens 2 supports more update automation features that HoloLens (1st gen), especially if you use Microsoft Intune to manage Windows Update for Business policy. These features make it easier for you to plan and implement update rollouts across your organization.

#### Plan the update strategy
Windows Updates for Business supports deferral policies. After Microsoft releases an update, you can use a deferral policy to define how long to wait before installing that update on devices. By associating subsets of your devices (referred to as *update rings*) with different deferral policies, you can coordinate an update rollout strategy for your organization.
For example, consider an organization that has 1,000 devices and has to update them in five ways. The organization can create five update rings, as shown in the following table:

**Example 2: Pause an update ring**
If you discover a problem while deploying a feature or quality update, you can pause the update for 35 days (starting from a specified date). This pause prevents other devices from installing the update until you mitigate the issue. If you pause a feature update, quality updates are still offered to devices to ensure they stay secure. After the specified time period has passed, the pause automatically expires. At that point, the update process resumes.
