Are registry cleaners safe to use?

from ClifNotes, Dec 2006, permalink _ Windows Tips


Letter from Eddie in Australia:

Hi Clif,


I have read a lot about "Registry Cleaners" and how they can clean up 1000s of unwanted registry entries. Are these programs safe for the "ordinary" person to use, and can you cause any damage to your computer?.


Kindest regards,




My response:

Hi Eddie,


There is some risk, but I've been using EasyCleaner for 3 or 4 years. About once a month does it for me. I'm guessing you wouldn't need to clean very often. Once every three months or so.


Have fun!




What is the Windows Registry?

Your registry is a huge database that holds an inventory or location of many files, folders, programs and processes that reside on your computer. This information is often used to to run and locate the files needed to perform tasks. When files and programs are added or removed, the registry is changed to track these changes. Over time the registry becomes larger and less organized because of the changes. This can lead to poorer PC performance.


Cleaning your registry can sometimes cause problems. I have had only one minor problem in all my time using them. Using a registry cleaner that "backs up" the registry before it makes changes, is the safest to use. Most of those listed below have this feature.


The debate on whether or not you should use a registry cleaner has never been clearly won. I once got involved with a discussion of this at the DonationCoder forum. I think Carol's response in that forum thread was a good warning. However, most folks never have a problem.


The best way to avoid registry problems is to make use of as many stand-alone or portable apps as you can. These types of programs generally don't use the registry or other external files.
