If you have made it to this article you most likely have concluded that you are in need of a registry cleaner for your Windows Vista or XP computer. Sadly, discovering the need for a registry cleaner is only half the battle. Next one must find which registry repair utility to choose, and there are many to choose from.
The registry is similar to the brain of the computer, it's where all the settings are stored. To put it simply, it is where the operating system goes to find out how to run itself. This is obviously a very important cache of information and as a result, it's a favorite for viruses. The worst viruses go straight for your registry and begin to add, remove and break file paths. To make matters worse, many anti virus programs such as Norton or McAfee will remove the virus from the registry and take the infected registry files with them.
All computers build up registry errors, whether from simple software errors or from viruses it does not matter. The very worst registry errors result in a fatal system crash and the only option is to either chuck the computer out the door or do a full system reinstall. Thankfully, most errors that occur are much less sever in nature. They simply slow the computer down a bit. Over time more and more of these errors build up, resulting in the slow performance many people experience.
Most registry cleaners out there will offer a free trial before you buy. This sounds great until the software is downloaded and the user finds out that the cleaner finds a host of errors but the utility won't fix them until the full version is purchased. Many of these errors are also fake errors contrived to make the user purchase the product.
There is one registry repair utility out there that offers what all others do not. XP Repair Pro offers a free 15 day trial during which all discovered errors are also fixed. Furthermore the program has a utility that also defragments a users registry. This is not to be confused with a normal defragmenter which every computer has. The XP Pro registry defragmenter is specifically designed to optimize the registry for the fastest speeds.
