Like other computer software, registry cleaners have their pros and cons too. Most of the registry cleaners do not work as promised, specially the free registry cleaners and registry optimizers. Either they don’t do the job or they are too aggressive and remove genuine registry items along the junk. This is a major drawback in registry cleaners and you should be extremely selective before you go ahead and buy a registry cleaner. Registry cleaning software is good for your computer, there is no doubt to that. However, only the best registry cleaner can do the job effectively, without causing any harm to the Windows registry. There have been reported cases where free registry cleaners have actually corrupted the Windows registry, so beware of free registry cleaners that are good for nothing.
The 2009 registry cleaner trends show that there are thousands of free registry cleaners available out there, however, out of every 100 registry cleaners, only 1 is actually designed/programmed to remove unwanted registry keys and improve the performance of the computer, without damaging the windows registry. We wrote a review of the top ten registry cleaners that can be pretty helpful in finding out the best registry cleaners. While buying a registry cleaner, the first question you should ask yourself, will the software actually clean up your computer’s windows registry? If yes, will it help your computers overall performance? This is a shortcoming with many Registry Cleaner software as they claim that their software provides a sure, logical and effective clean up to your system but in truth sometime this claims are totally untrue, or half truths at most. Fraudulent software vendors will send you nothing at all and in most cases, there is no way to prove that Registry Software has had an effect on your PC. In fact, it is almost impossible to tell that your PC has had any improvements since the clean – despite the many promises by the vendor. The other of course is registry damage and most notably, is that which experts say, and they tend to agree, that there is no reliable way for a third party program, such as Registry Cleaner, to positively know that any one particular key is invalid, or no longer in use. Registry Cleaners are therefore, prone to dislodge files that are in use by the computer – by wrongly estimating that they are not in use.
This leads to bigger problems for the user – more detrimental issues that in most cases cost much more to troubleshoot and repair. Performance benefits, really? In Windows XP, Vista, Windows 7 and beyond the possibility of Registry Cleaner causing significant improvement in the performance of the operating system and hence computer are very marginal. Because the registry cleaner removes just a few kilobytes of redundancy, think about it… a few kilobytes in a day when RAM alone has a capacity of more than 1 GB and internal bus runs on more 264 bytes per second. Please this is a drop in a wide, wide ocean and the claim that removing a little redundancy would make an incredible change is just that, incredible. The idea then is to consider your options, a possible insignificant performance change or the possibility of system instability. Then there are those keys that prove formidable for any Registry Cleaning Software: These are Undetectable registry keys. Registry cleaners cannot repair undetectable registry keys, they are untouchable, they are caused by null characters in their names that are embedded such that it is impossible for the software to remover them. In these cases only specialized tools like the RegDelNull utility are able to remove such a file and no Registry Cleaner can, another shortcoming. No matter what anyone says no single Registry cleaners can remove malware in a Registry. Registry Cleaners do not have such functionality, they do not have specialized malware removal programs, meaning that they are equipped to deal with complicated software spyware, and adware. Therefore, viruses and Trojan programs can re-infect a computer through by using the tool to replicate as the clean up process continues. This is a bad scenario for any PC user considering doing a registry clean; ensure your program is malware free prior to initializing the program. Recovery capabilities, for most Registry Cleaners, a corrupt registry is gone – a write off. The programs do not have functionality to allow you recover a damaged registry.
This means that if your registry cannot be supported by a system, due to one problem or another in the registry, registry cleans up programs cannot play any role here. You will need to use specialized and more advance tools like the Automated System Recovery, from a “Last Known Good” boot menu, run under Microsoft. The other is fact that Registry cleaning software does not have functionality to handle virtual registry applications – that is application based on virtualizes registry entries. Registry cleaning software has several shortcomings, the most glaring being obviously the fact that with today’s technology – large working memory (RAM), fast internal bus speeds, and high speed processors – that they only provide a few kilobytes of reprieve to such systems are redundant in itself: This, besides the fact that may as well cause the entire computer to breakdown or be very unstable. And the fact that it is very difficult to substantiate their actual impact on the performance of a computer good or bad. The ultimate decision to use Registry Cleaners lies on your need to create an optimally operating PC and the risk involved, it swings either way.
