Your computer runs many programs you may not be aware of in addition to the programs you are running (i.e. email, web browser, media player etc.). In order to keep track of all programs, your computer uses a database called "registry". The registry contains instructions on how to open every program on your computer. As time goes by, the registry becomes cluttered and unmanageable. This slows down your computer, makes it more error prone and less secure. The only way to correct these issues is by cleaning your registry. Here we discuss one possible means of cleaning the registry: By utilizing registry cleaner software.

Registry cleaners are designed to scan the Windows registry for mistakes, duplications and corrupted files and resolve these issues (this scan is similar to a virus scan). Some cleaners are also capable of organizing the registry so it is in one centralized location so your computer can find files easily - this is called registry optimizing.

When choosing a registry cleaner, there are several things you need to consider. Below are a few of these things:

*Freeware v. Purchased software: It is generally recommended that you use freeware for diagnostic purposes only. Most freeware is outdated and full of bugs. You can also opt to using a free trial version of purchased software. This will allow you to "test drive" a cleaner before you buy it, and will allow you to clean your computer for free.

* PC Optimizer: Although a PC optimizer feature is not strictly necessary, it is good to have. PC optimizing can enhance your computer and make it much faster than if you use cleaning alone.

*Auto backup feature: Any registry cleaner you choose should have a backup feature. This is a safety measure in case an important file got erased from the registry during cleaning. If your cleaner does not have this capability, you may find yourself spending time and money trying to restore your computer to a working condition.

* Complete error removal: Your cleaner of choice should remove all types of errors and not just some types.

In sum, if you follow these guidelines, you should be well on your way towards a cleaner, more efficient computer.
