Problem:

I want to be able to inventory a certain Registry key. How do I do this in ConfigMgr?

Resolution:

Unlike SMS 2003 where you modified the SMS_def.mof, in ConfigMgr you may need to modify both the SMS_def.mof and the new Configuration.mof file introduced with ConfigMgr. This is not as straightforward as it could be and my best advice is if you find yourself needing to do this is to use Mark Cochrane’s fantastic free “RegKeytoMof” tool which you can download from here.

Once you’ve downloaded the tool use this excellent post by Sherry Kissinger who walks you through using the tool mapped to a “real world” example:
