Purpose: Gather a new registry value that is not included in the built-in values.
SCCM has a long list of Hardware Inventory objects that you can set the system to gather for you from each workstation. As you continue to use SCCM more intensively, you will notice that the built-in list is not comprehensive for all your great ideas. Thats when you need to extend the SCCM 2012 Hardware Inventory and gather the registry values that you have noticed to be important for you. This will take a moment, so dont rush it.
