The reason this question is so important is simple. Your registry is one of the most intricate yet delicate parts of your computer. It is a catalogue of many different things your computer needs to know. For instance, your personal preferences and hardware profiles are saved in your registry. In addition, your registry logs interactions between different programs so it can look out for conflicts. These things are constantly being recorded again and again in your registry and, after a time, it becomes very full. If you don’t keep it clean and organized, your computer’s performance can suffer dearly.  

So back to the question, “are paid complete registry cleaners better than free registry cleaners?”, it is best to pay for a registry cleaner. You can do the review yourself online when it comes to choosing one, but free registry cleaners usually aren’t “free”.  The manufacturer may offer a free trial period, but eventually, to maintain your system and a registry backup, you’ll end up purchasing an update.  That is, if the software has an update. You may run into issues with customer support as well.  Most free registries claim that they offer technical support, but it can lack thoroughness as the company may not have adequate funds needed to simply pay staff.

With a purchased registry cleaner, you also end up with access to upgrades and real tech support, rather than just the FAQ you get with a free cleaner. If that still isn’t enough to sway you, you might be interested to know that a piece of software compiled by a major company is far more likely to have gone through extensive testing and therefore be a better-written piece of software. When a company is staking their finances on a program, you can bet they will try to resolve all possible problems.

That still doesn’t mean that everyone out there is going to run out and pay for a registry cleaner. Sometimes the free versions can be too persuasive. Just make sure that you read as many user reviews of the product you choose as you can. Honest user reviews will help you ascertain if the program can really  speed up PC performance as you want it to. While the best complete registry cleaner is not always the most expensive, keep in mind that you do get what you pay for.
