You can configure active hours for devices without setting the **Configure Automatic Updates** policy. *Active hours* identify the period of time when you expect the device to be in use. Automatic restarts after an update will occur outside of the active hours.
By default, active hours are from 8 AM to 5 PM on PCs and from 5 AM to 11 PM on phones. Users can change the active hours manually. Additionally, administrators can use Group Policy or MDM to set active hours for managed devices.
By default, active hours are from 8 AM to 5 PM on PCs and from 5 AM to 11 PM on phones. Users can change the active hours manually.
Additionally, administrators can use multiple ways to set active hours for managed devices:
- You can use Group Policy, as described in the procedure that follows.
- You can use MDM, as described in [Configuring active hours with MDM](#configuring-active-hours-with-mdm).
- While not recommended, you can also configure active hours, as descrbied in [Configuring active hours through Registry](#configuring-active-hours-through-registry).
### Configuring active hours with Group Policy
To configure active hours using Group Policy, go to **Computer Configuration\Administrative Templates\Windows Components\Windows Update** and open the **Turn off auto-restart for updates during active hours** policy setting. When the policy is enabled, you can set the start and end times for active hours.

### Configuring active hours with MDM
MDM uses the [Update/ActiveHoursStart and Update/ActiveHoursEnd](https://msdn.microsoft.com/library/windows/hardware/dn904962.aspx#Update_ActiveHoursEnd) settings in the [Policy CSP](https://msdn.microsoft.com/library/windows/hardware/dn904962.aspx) to configure active hours.
To configure active hours manually on a single device, go to **Settings** > **Update & security** > **Windows Update** and select **Change active hours**.
### Configuring active hours through Registry
![Change active hours](images/waas-active-hours.png)
This method is not recommended, and should be used when neither Group Policy or MDM are available.
Any settings configured through Registry may conflict with any existing configuration that uses any of the methods mentioned above.
You should set a combination of the following registry values, in order to configure active hours.
Under **HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate** use **SetActiveHours** to enable or disable active hours and **ActiveHoursStart**,**ActiveHoursEnd** to specify the range of active hours.
For a detailed description of these regsitry keys, see [Summary: Registry keys used to manage restarts after updates](#summary-registry-keys-used-to-manage-restarts-after-updates).
