Registry HOWTO format

I've been working out some ideas regarding a HOWTO for the Registry and wanted to post what I'd come up with so far, and solicit thoughts and ideas on the format. So far what I've got is:

• A description of the Registry (gotta get us all on the same page)
• What is stored in the Registry?
• What to look for in the Registry when dealing with specific issues/cases (ie, CP, malware, intrusion, etc.)

What else would be of value?

Oddly enough, I haven't received a single comment to my "The Registry as a log file" blog entry. I thought that perhaps that one would be controversial enough so that someone would at least tell me that I'm out of my mind. So...either I'm completely on target, or I'm so far off base with that one, no one wants to even acknowledge it. ;-)
