I have an automatic patch group called "Servers Manual Update".  My intention is to have all systems in this group to scan, download, and then wait until I take an action to start installing patches.

I have some test machines in this group now, and it looks like everything worked as scheduled.  I clicked on the link to start deployment expecting to select which machines to deploy, but instead it just said the deployment has been initiated.  I understand it says "Yet to Apply" because I have the deployment policy associated with the task for 19:00:00 - 08:00:00.

Is there a way to cancel deployment once the status changes to Yet to Apply?

Now, if I click on one of these computers at the bottom, I can get the Missing Patch View just for that workstation. There are checkboxes next to each patch, but I can't take any action.

Why are the checkboxes there if I can't take any action? How do I access the drafted configuration and control the deployment?
