How much do you trust registry cleaners?

I've always used ccleaner to clean the registry when i uninstalled something. Hasn't messed up my system yet.

when they work there great when they fail they break your computer.

does that help? cc cleaner good though

My take on this is.....

.....ordinary users should NOT use ANY registry cleaner. PERIOD.
EVEN CCLEANER.

Unless you are a trained professional who knows exactly the consequences of altering the registry entries it is not if, but WHEN you will have serious trouble which may result in having to reinstall the OS.

For the most part like some others said you will gain the most increase in performance with a basic windows defrag, cleanup up of temporary files, and selecting programs on start up. That being said you must ALWAYS allow your security suite to boot on start up.

CCleaner, when left at it's defaults, is perfectly safe to use for all users.

The default state for CCleaner's registry app checks everything. Seems like a potential for trouble somehow, some way.

I think CCleaner themselves only recommends some of the categories be universally removed.

If you're worried about CCleaner Registry cleaner then accept its offer to back up the changes and/or set a System Restore Point - Create

After 15 years, still waiting for a single documented case of it harming a system.

Why when so many of our experts quite rightly warn of the dangers of messing with the registry is there here on this very page (viewing without signing in) an advert for a windows optimisation software (Regcure)
