Data Collector with Windows Perfomon

Where from do I choose to capture HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run registry key in Windows Perfmon? I created a New User Defined Data Collector Set (manually). I checked Performance counter and System configuration information (?) in the next window and I am stuck at which counter to add for the above key. Thank you in advance.
P.S. I am so frustrated with this I am about to do the Office Space scene!

what information are you trying to capture through perfmon?

ASP NET events trace, HKLM->SOFTWARE->Microsoft\Windows->CurrentVersion-> Run registry key and Database->I/O Log reads/sec. I found the first and third, it's the second one I have trouble with.
