Resolve application failures

In the Activity Manager view, click the Applications tab. You can view all the applications on all machines to which this user has access, including local and hosted applications for the currently connected machine, and the status of each.

The list includes only those applications that were launched within the session.

For Multi-session OS machines and Single session OS machines, applications are listed for each disconnected session. If the user is not connected, no applications are displayed.

Action Description
End the application that is not responding Choose the application that is not responding and click End Application. Once the application is terminated, ask the user to launch it again.
End processes that are not responding If you have the required permission, click the Processes tab. Select a process that is related to the application or using a high amount of CPU resources or memory, and click End Process. However, if you do not have the required permission to terminate the process, attempting to end a process fails.
Restart the user’s machine For Single session OS machines only, for the selected session, click Restart. Alternatively, from the Machine Details view, use the power controls to restart or shut down the machine. Instruct the user to log on again so that you can recheck the application. For Multi-session OS machines, the restart option is not available. Instead, log off from the user and let the user log on again.
Put the machine into maintenance mode If the machine’s image needs maintenance, such as a patch or other updates, put the machine into maintenance mode. From the Machine Details view, click Details and turn on the maintenance mode option. Escalate to the appropriate administrator.

Disable the visibility of running applications

By default, the Activity Manager displays a list of all running applications for a user’s session. This information can be viewed by all administrators that have access to the Activity Manager feature. For Delegated Administrator roles, this includes Full Administrator, delivery group Administrator, and Help Desk Administrator.

To protect the privacy of users and the applications that they are running, you can disable the Applications tab to list running applications. To do this, on the VDA, modify the registry key at HKEY_LOCAL_MACHINE\Software\Citrix\Director\TaskManagerDataDisplayed. By default, the key is set to 1. Change the value to 0, which means the information is not collected from the VDA and hence not displayed in the Activity Manager.


Editing the registry incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
