How to Use Custom Inventory for Windows to Gather Registry Information from Multiple Keys

It is possible to write custom inventory to gather data from more than one registry key. An example follows and is also found in the custom inventory samples repository (seek KB# 4237).

Notes:

1. Apparently, the logic starts at the bottom key and works its way back up. So, we need to store the type and identifier values until we get back to the dmaenabled property.
2. We can only clear out the curtype and curidentifier variables once we get back to the dmaenabled property. Otherwise, they'll be blank when we need them to populate the z:row data.
