You are the systems administrator for your company. The network consists of a Windows Essential Business Server 2008. You use System Center Essentials 2007 to manage all client computers on the network. You deploy an .EXE application on all managed computers by using System Center Essentials 2007.

After a few months, a new version of the application is released. You want to install the new version of the application on the managed computers. Before deploying the new version of the application, you want to uninstall the old version of the application deployed on client computers. Your solution should use the least administrative effort.

What should you do?

A.
Right-click the application in the All Software Packages pane in the Essentials 2007 console, and select the Approve for Uninstall option.

B.
Right-click the application in the All Software Packages pane in the Essentials 2007 console, and select the Delete option.

C.
Open Add or Remove Programs snap-in on each managed computer, and uninstall the application.

D.
Run the New Software Package Wizard to create an uninstall package for the application.

Explanation:
You should run the New Software Package Wizard to create an uninstall package for the application. You can use the System Center Essentials 2007 console to uninstall previously deployed software from managed computers. When Essentials 2007 uninstalls software from managed computers, it uses the uninstall parameters that are specified in the Essentials 2007 software package. While creating a package for deploying .EXE applications, you can specify the installation parameters and specify whether to add the application to the Add or Remove Programs snap-in, but you cannot specify removal parameters for .EXE applications. Therefore, to remove .EXE applications, you should create a new uninstall package by using the New Software Package Wizard to specify the uninstall parameters for the application.
You should not right-click the application in the All Software Packages pane in the Essentials 2007 console, and select the Approve for Uninstall option. The Approve for Uninstall option is only available for Windows Installer applications. In this scenario, you want to remove an .EXE application, which requires a new uninstall package to be uninstalled by using System Center Essentials.

You should not right-click the application in the All Software Packages pane in the Essentials 2007 console, and select the Delete option. Selecting the Delete option only removes the software package from the System Center Essentials server. It does not uninstall the software from managed computers. Also, before deleting a package, you must specifically approve it for uninstall to be able to uninstall the software from managed computers.

You should not open the Add or Remove Programs snap-in on each managed computer and uninstall the application because uninstalling the application manually from each managed computer would require more administrative effort than is necessary.
