CCleaner usually finds a big list of registry entries designated as

I've no idea what they are, but I always tell it to remove all of

Consider yourself lucky. Let me point out that neither I nor anyone
else who warns against the use of registry cleaners has ever said that
they always cause problems. If they always caused problems, they would
disappear from the market almost immediately. Many people have used a
registry cleaner and never had a problem with it.

Rather, the problem with a registry cleaner is that it carries with it
the substantial *risk* of having a problem.

Define "substantial".


And since there is no benefit to using a registry cleaner

Really? If it would solve the OP's problem, I'd say there was a benefit.
