I've always been very apprehensive about registry cleaners. There have been a lot of
conversations about them in the newsgroups, and not much of what is said is favorable.
Just to see for myself, I decided to try Comodo's product. I did a "Normal" clean on my system.
Apparently, it removed a bunch of stuff that didn't need to be in there, but some of the items
were regenerated as soon as the next restart. On balance, I guess I'd have to say that there
hasn't been any perceptible improvement in performance.
That was two weeks ago. I guess I'd have to count myself as lucky that no damage was
done; at least nothing that I've spotted so far.
If you're going to attempt to use a product like this, it's always a good idea to create a restore
point, and also back up the registry beforehand. Free utilities are available for this purpose.
Regards.
