The registry used by the Windows operating system is a complex set of instructions.
They are essential commands that the system needs to run your computer properly.
When the system becomes sluggish or does not boot up at all the culprit is usually errors in those files.

The causes of these errors are frequently redundant or obsolete entries, and/or vacant spaces left behind when a program is removed from your computer.
Be sure that when a cleaner is chosen you pick one that is right for your particular operating system.
Each operating system uses a different approach to the storing of information in the registry.
Therefore if you do not use a cleaner that is compatible with your version of Windows then more errors could result.

Data can be accessed quicker due to another feature of a good cleaner.
The data can be rewritten so that it is stored in a contiguous manner in a process known as defragmentation.
