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.

In my case, it's *never* caused a problem, and I've been using it to
manage several computers for several years. I appreciate that it
*could* cause problems, but so could lots of things, and it simply
hasn't. It seems sensible to me to take precautions appropriate to the
level of risk.

Rather, the problem with a registry cleaner is that it carries with it
the substantial *risk* of having a problem. And since there is no
benefit to using a registry cleaner, running that risk is a very bad
bargain.

What's the worst that could happen? I might have to reinstall Windows,
then do a bit of reconfiguring, a tedious task but one I've done so
often I could do it in my sleep. I wouldn't lose any of my
irreplaceable data because it's on a different drive within the
computer and I have external backups as well. I worry about things
that need worrying about, but not this.
