Don't say by getting rid of unneeded data. Give a LOGICAL explanation.

I can think of one scenario where the use of a registry cleaner might improve
performance, but it would require the use of two additional programs. Here's the
four-step process:

1. use registry cleaner
2. defragment volume that contains registry
3. use registry compacter (eg, NTREGOPT)
4. reboot system

Using this process, NTREGOPT will create a new, smaller registry that will not
be fragmented. Defragmenting the registry in this fashion WILL have a positive
impact on performance, particularly during the boot process when large chunks of
the registry are manipulated.

Now, one can argue whether the performance boost was due to NTREGOPT or the
registry cleaner, but that's for others to debate. For what it's worth, I use
NTREGOPT every couple months, but I never use a registry cleaner. For many
reasons, I perform registry cleaning tasks manually...
