What a joy it is day in day out to deal with Registry corruption or, at least, Registry internal inconsistency. A rather popular Registry Cleaner utility (not recommended by any means by Microsoft) crashes on my machine because the Registry is messed up. Not by me, but by certain very, very expensive commercial software vended not by Microsoft. I'm now running the Recovery Partition to reinitialize the Registry so I can proceed. One day computers will have either a Registry that will not become internally inconsistent or some better designed catch basin for the memory hole.
