Hi All

What do people think of registry cleaners? I have heard pro and cons of each. Are they any more reliable these days.

Thanks, Doug

Here is BC's view on registry cleaners:

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:

• Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.

• Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.

• Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.

• Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.

• The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.

I agree with the above quote 100%.

As I've said many times on this forum, registry cleaners, tune-up programs, and so-called "optimizers" are the current snake-oil of the internet. There are countless free programs like this and apparently some paid ones, as well.

Do not be deceived. They promise performance you can only dream about....but only deliver a computer that is worse off than it was to begin with.

Thanks for the quick reply's. I have stayed away from them. Some people I work with use them a lot. The computer in question runs real slow. Celeron 2.4ghz 512 mb of ram. My nephew uses it. Found some bugs and removed them with Malwarebytes. Avg did not find anything. Ran TFC cleaner and used Auslogics to defrag. Does not show anything processes running in the back ground. Trying to speed it up some.

Thanks, Doug

I primarily use Ccleaner since it is mild unlike many aggressive cleaners out there and since it has a backup function also. If your registry cleaner doesn't have a backup function you should find a program like Erunt for example that will back up the registry before you modify it.

Adding ram to that computer will really help.

Yeah, a Celeron with 1/2GB RAM is going to run slow regardless of what you do to it. Deleting a few "missing shared dll's" won't increase speed by any stretch of the imagination.

Removing malware, temp files, and defragging will help some....but slow hardware is still slow hardware.
