Ongoing or scheduled refresh, recompose, or rebalance tasks can be paused, resumed from a pause, or canceled at any time using the Horizon Administrator console. When a maintenance task is canceled or paused, any operations currently underway will finish, but no new operations will start. When a paused task is resumed, the maintenance operation will continue. When managing these maintenance tasks, you should bear in mind the following two facts:

• The resources required to perform Horizon maintenance tasks may impact the performance of the Horizon infrastructure. If Horizon maintenance tasks are causing performance problems for Horizon desktops that are currently in use, or for other resources that share the infrastructure, simply pause the maintenance tasks. Resume the maintenance tasks during a period of reduced infrastructure utilization.
• I do not recommend canceling maintenance tasks, as this may leave the desktops in an inconsistent state; if the maintenance operation is causing performance issues, simply pause it until there is a more suitable time for it to be undertaken.

The following steps outline how to manage a task that is assigned to a desktop pool or an individual desktop:

1. Log in to the Horizon Administrator console using an Active Directory (AD) account that has administrative permissions within Horizon.
2. Go to Catalog and open the Desktop Pools window within the console.
3. In the Desktop Pools window, click on the pool that has the task that you wish to cancel. In our example, we will click on the pool called AppVolumes-W10 to open the AppVolumes-W10 window.

4. Under the Tasks tab of the AppVolumes-W10 window (as shown in the following screenshot), highlight the task that you wish to update and click on Cancel task..., Pause task..., or Resume task..., as required. Since the sample task is not currently paused, the Resume task button is grayed out:
