There are a lot of registry cleaners out in the market but the problem now is which cleaner is the best and which will cause you more problems in the near future. Almost all cleaners have different features and this might be a bit confusing to those who are new to the software.
Some are very good at doing the job while some are just plain lousy and will even mix up all the files that they are supposed to clean up.
Registry cleaners are made to do one important job. That is to fix and remove all files that are not being used by the computer. By removing all these unwanted and unused files, your computer will run faster just like it was new.
The windows registry is the main database of your computer. This is where all the files are kept and all the programs run by the computer goes through. The computer opens and closes all these programs at lightning speed and chances are, the computer mixes them up and makes errors.
Some programs hitch a ride from other programs. This is what happens with computer viruses. When you try to download a program especially over the internet, a virus or any form of spyware or malware will hitch a ride on the downloaded file and will cause serious problems on your computer.
Registry cleaners are created to scan through your registry files. The program checks each file and either fixes or remove those that deem to be corrupt or broken. You should also make sure that when you do use the registry cleaner software that it should be able to detect all the problems on your computer and fix them according to the problem in a safe manner.
Most of the time, a lot of free cleaners that are out in the market are pretty much useless. You can get them for free and some instead of cleaning up the registry end up deleting all the important registry and windows files.
The reason this happens is not because they are malicious, but because they are not updated and do not recognise many of the files they are scanning.
A good registry cleaner will back up your registry, be updated frequently and remove all the errors on your computer which is slowing it down.
