Uninstall patches (patch rollback)

You can uninstall (i.e., roll back) patches that have been deployed to managed devices. For example, you may want to uninstall a patch that has caused an unexpected conflict with an existing configuration. By uninstalling the patch, you can restore the device to its original state.

To uninstall or roll back a patch

1.View the properties for the definition associated with the patch. Right-click the definition and click Properties.

2.In the Detection Rules list, right-click one or more rules and then click Uninstall.

3.Enter a name for the uninstall task.

4.Specify whether the uninstall is a scheduled task, a policy-based scan, or both.

5.If you selected scheduled task, specify the devices from which you want to uninstall the patch.

6.If the patch can't be uninstalled without accessing its original executable file (i.e., using command-line parameters), and you want to deploy the executable using Targeted Multicast, select the Use multicast check box. To configure Multicast options, click the Multicast Options button. For more information, see About the Multicast options dialog box.

7.If you selected policy, and you want to create a new query based on this uninstall task that can be used later, click the Add a query check box.

8.Select scan and repair settings from the available list (or create custom settings for this scan), to determine how the scanner operates on end-user devices.

9.Click OK. For a scheduled task, you can now add target devices and configure the scheduling options in the Scheduled tasks tool. For a policy, the new policy appears in the Application Policy Management window with the task name specified above. From there you can add static targets (users or devices) and dynamic targets (query results), and configure the policy's type and frequency.

If a patch installation failed, you must first clear the install status information before attempting to install the patch again. You can clear the install (repair) status for the selected device by clicking Clear on the Security and Patch Information dialog box. You can also clear the patch install status by vulnerability.

Remove patches from the core database

To remove patch files permanently, you must delete them from the patch repository, which is typically on the core server.
