The main reason is that software companies wish to reach and introduce themselves to as large an audience as possible. If you use a computer, you need free registry cleaners as much as you need any other program you have, if not more, especially if you are a first time computer user. Free registry cleaners are one of the first non operating system pieces of software that a new user needs to download and install in order to insure against future system slowdown or breakdown.

Without a registry cleaner, clutter and error causing files or conflicting preference settings will accumulate in your Windows registry database and cause your system to slow to a crawl, programs will crash more frequently, or your PC may simply one day fail to respond at all. Aside from having a virus, adware, or other malware infestation problem, registry errors are probably the number one reason that a person’s computer system ceases to function at its top potential, or error messages begin to appear for apparently no reason whatsoever.

While giving free registry cleaner software away introduces you to the software firm, and an agreement is usually made by you to allow them to contact you with other software offers, the registry cleaner itself is one of the most valuable pieces of PC maintenance products you will ever download and install.  And it is this value, and almost total market demand, that makes a free Windows registry cleaner one of the most sought after, thankfully accepted software products that a company can offer, at any price.

Not all free software is created equal. The best free registry cleaner will help to maintain registry system health, improve program responsiveness and general computing speed. Several programs even allow you to edit your hardware and software settings so that you can reduce the workload on your CPU and memory, allowing you to get more work done with fewer resources wasted.

Your Windows registry is the central database that stores some of the most frequent changes to your computer. Everything from hardware settings to personal profile customization records are stored here. It is easy to see, that over time, the aggregate of these system change files can begin to build up, become confusion, or even contain information that eventually causes conflicts or confusion within your computing environment.

Using a free registry cleaner is the best way to ensure that your PC continues to run in the same speedy, jaw dropping performance that you initially bought it for. Downloading free registry cleaners is good for you. Why they give them away is really irrelevant, as I am, and I hope you are, simply happy that they do.

A registry cleaner review will evaluate the different features, upgrade options, additional accessories, and even complete desktop optimization system integration. The limits of a software company’s imagination are also the limits of the different option, bells, and whistles, or even crippling limitations, that come with a product by default, or can be offered as an addition upgrade or add on.

Several of the registry cleaners on the market will also do registry error removal, but not all of them. Regcure is one of the most reliable and popular registry cleaners on the market that offers all of the most advanced features including virus and spyware scans and removing start up programs that slow down your computer. A registry cleaner comparison chart highlighting different software programs side-by-side gives you a glance at the pluses and minuses of the most popular software.

Another popular software is Max Registry Cleaner which finds incorrect or obsolete information in your registry and safely repairs it. The modest cost of this software is nothing compared to the high price of having a computer technician solve your registry problems for you.

The method of allowing for scans but not removals was made popular by virus and adware removal software campaigns, some even created or promoted by the same companies. You can usually get more out of a free registry cleaner that offers several upgrades or add on features, as the makers of these free registry cleaners make more of their money off of the add ons and other services provided, and are more likely to not only scan, but remove errors for you to increase their distribution.

A good registry cleaners review will be sure to mention the licensing details of registry cleaning software. While much of the software on line is commercially licensed freeware with a charge for add ons or specific features, there are also free registry cleaners that are time limited shareware. This software license allows you to use the product for a specific, predetermined amount of time, fully unrestricted, but at the end of that time period, will “cripple” the software, requiring you to register the software to “unlock’ it. While this may seem alarming, it is usually a painless and simple process to restore full usability, usually by signing up at the software promoter’s website, or through the purchase of the registration key from the company.

One free registry cleaner option that is becoming more and more popular today is the use of open source products. The licensing of these products allows for free or commercial distribution, but allows anyone to see and/or modify the code to their liking. While this option might seem more agreeable to the more technical oriented in the crowd, the major advantage for the initiate user is that a free registry cleaner licensed under the open source model (especially under the GPL), is that they are more likely to be fully functional, complete registry error suites.

Lastly, when trying to choose between the many registry cleaners out there, check out registry cleaners reviews that feature compairson charts of the different options the software offers. A side by side chart like this will make it easy to find the software that is right for you.
