What's the story with registry cleaners? I'm noticing that some people love them and some people hate them. I have personally experienced significant speed increases after running Ccleaner. Should I worry that I am messing up my computer?

registry cleaners are really only of use if you regularly install and uninstall software - the leftovers can slow down your system and/or sometimes cause issues.

for most people they arent that useful.

There is a lot more performance to be gained for most people by doing the temp file cleanup part of ccleaner

Some people insist that registry cleaners are terrible and don't even help. Is there a basis to that?

>> ...Is there a basis to that?

Mostly personal experience. Thought some "testers" back that up.
Most I have seen are more or less null, as far as help or hurt goes.

I have been using them for 10+ years (since W98) and only had 1 problem.
I was trying a new cleaner and the system would not reboot afterwards. But it turns out the hard drive also had issues, so who knows what actually trashed it.

Never really noticed a big improvement after using a reg cleaner, though a few "never been touched" systems seemed a little perkier.
I just like the idea of keeping my reg "tight".

Like wolfcamel stated, more noticeable are cleaning junk files and defragging.
I run the Ccleaner File cleaner every night before logging off. I have it set to flush everything but Cookies.
The Reg cleaner maybe once every 2/3 months or after installing/uninstalling software to play with.

the cleaners in itself are not bad - it's how you use them
if you let them clean on "automatic" you put yourself to their mercy - and don't know what is deleted or changed
so i never do that; if i have to remove leftovers from an install, i use regseeker which lists ll entries for the searched program, and these can be deleted in one go

also -as noted, i never saw anythuing running better after they had been used - unless a program was corrupted, and the cleaner removed the "residu"

personally i dont use registry cleaners. Most of them, if left to run automatically will not really clean well, and sometimes even remove something that should not.
I dont see any difference in speed if you clean the registry, as the registry itself is not too big for current processor to read/write when loading it.
I prefer cleaning the registry manually, but this required extensive knowledge on the registry, but it is much safer then using the automatic cleaner.
