There are several ways to cancel a patch deployment.
•Immediately following the initiation of a patch deployment, the Operations Monitor appears and displays the status of the steps in the deployment preparation process. You can use the Stop deployment button to cancel any deployment that is still in the preparation stage.
•After the Operations Monitor shows that the deployment preparation process is complete, you can right-click on a scheduled job in either Operations Monitor or Deployment Tracker and select Cancel deployment. You can cancel scheduled deployments on multiple machines at one time.
•You can use the Scheduled Remote Tasks Manager to delete any patch deployment tasks currently scheduled on any of the machines in your network. Simply right-click the task(s) and select Delete.
•You can select a deployment in the Results list of the navigation pane and use the right-click menu to cancel the deployment.
