Windows 7 - Registry Cleaners

do CCleaner actually sometimes ruin the windows 7 systems??? or any other registry cleaner?? give me some opinion..
because i have the following softwares and what do u prefer??
*CCleaner
*Perfect Optimizer
*RegCure
*MZ Registry Optimizer
*PC Registry Mechanic
*Paretologic PC health

Win 7 doesnt really need them and all of them top to bottom can do more damage than they fix.

If I was forced on pain of death it would be CCleaner. But not automatically

Are you a highly skilled computer user? ...

If you do not have knowledge of the registry, then you would probably be better off leaving it alone, and definitely not placing blind trust in a program to do the job for you.

IMO - there is no reliable way for a third party program to know whether any particular key is invalid, redundant or neither. Some registry cleaners may not know for sure whether a key is still being used by Windows or what detrimental effects removing it may have. This has led to examples of registry cleaners causing loss of functionality and/or system instability.

Agreed: My more recent experience with them is more using them as a filter, that I then have to go over and look at every entry for. It's not something I would recommend to someone without a prior knowledge of the registry as well as their own hardware/software.

Although far from proven, and I have no scientific data to back up my claim.

I wouldn't be surprised if some of these registry cleaners are causing this SP1 debacle. I'm not saying any names, but there's some on this list that are widely used and trusted.

Thanks but im just average user.. .was there any windows program that would help speed up and clean system clutters??im using perfect optimizer 5..on my netbook..it speed up my netbook than before.
do you suggest that i stop using it??
and how about the left overs from uninstalled programs in registry..
any software that is much more safe?? Thanks for the response.

Unless you're a highly skilled and knowledgeable user, it's really risky using any registry cleaners or optimizers of any kind.

Extra leftover registry entries don't hurt anything, and unless you are digging around in the registry, you would never notice them anyway. Best bet is to not worry about it. It can cause more problems than it fixes. I know for most people it's just the idea of the registry being as "clean" as possible, and it makes them feel better about their pc, but it really doesn't make a difference.

There's a reason why CCleaner and other registry cleaner have a backup option......because yes, they can screw things up.

I too, if I had to choose....it would be CCleaner.

Yep.

Disk Cleanup Utility - Built into Windows.

If you follow what is listed below your system should run well...

*Do you do your computer housework on a regular basis?

Eg
Check Disk.

Disk Clean Up
Error Checking
Temporary Files Removal

* IE.8 - Safety - Delete Browsing History. -
Check for unwanted plug ins.
* Open IE8
* tools
* internet options
* advanced
* reset

*Make sure your windows Update is running.

*Have you checked in Task Manager/ Processes/ All Users to see what is running there?

*Do you check in Event Viewer for errors frequently?
Note any with a red mark in Application & System.

* Monitor regularly >Perfmon - {Task manager - resource monitor - CPU, Memory etc}

*Remove any software you have evaluated and decided you don't want to keep.

Run: SFC /scannow (from a command prompt) - and let it check/repair/verify your system files

*Some people optimize and compact the registry. This makes me VERY nervous and consequently I don't.
