After doing some more work with Process Monitor I found the leaks to be stemming from a driver associated with a License Manager from SafeNet Inc. which runs on the machine.

The vast majority of the handles are of type "Key". I can find them in the registry.

The sample that you posted is for the "Tablet PC Input Panel Text Services Framework" [1]. However, I find it strange that a) IIS needs this and b) that it would leak it. Are you able to obtain a large statistical sample of the leaked registry keys? 2 out of 130,000 seems like a small sample. Try the command line "handle.exe" tool [2]. It can dump to a text file that you can then analyze with perl, python, grep, etc... or your own eyeballs. :) See if the handle list is dominated by a specific set of registry keys.
