I wouldn't say he is "against the grain". This certainly is my and his
opinion which is shared by many knowledgable techs. There is no advantage
to running a registry cleaner, but there is a significant downside to it.
You are at the mercy of what the cleaner decides is not needed. The problem
is that they can remove something that is later needed, then the OP runs
into unexplained problems and many times is removed sufficiently from the
cause that they dont' realize what did them in.
There has never been any objective proof showing they are of value. Of
course there is a reason for them, to separate the unknowing folks from
their money. I call them snake oil products just like free memory
We regularly get posts in here where problems are created by their use, but
rarely get a post where it helped. The only way to use one is when you are
trying to troubleshoot a problem with a certain software. Run it to see
what it finds, and then research to see if anthing is related to the issue
at hand. Based on that research manually make the necessary changes, always
making sure you created a system restore point first and made a backup copy
of any reg keys you plan to change. Even better use ERUNT to make a
complete backup of the registry on a regular basis.
There are hundreds of thousands of entries in the registry. Removing a
handful that are orphaned is highly unlikely to help, particularly since
unused entries don't in and of themself cause problems, but removing the
wrong entry can cause lots of problems.
Don't use one.
Here is one on going thread discussion about the use of registry cleaners.
Defragging a hard drive is of less importance than people place on it. Yes
it can make a significant difference in some situations and when the drive
starts to fill, but rarely does it make a difference to the average user.
That is why 3rd party defraggers are not needed for most folks. The in
built one works fine, defragging once a month or so. Rarely does it have a
significant impact. As drives get larger and faster, and as memory
management improves, for example with Vista, where there are significant
improvements in memory management, defragging has an even smaller impact.
