Gizmo's Freeware Reviews: Best Free Registry Cleaner
1 February 2012

Introduction
The registry is what keeps your computer running; it tells the computer what to do when certain events happen. However, as you use your computer, a lot of unwanted and unnecessary information is written into the registry, and this usually occurs because you've installed and uninstalled programs or updated versions of existing programs. This gradual accumulation of unneeded or incorrect information will, over time, slow the speed of your computer.
A registry cleaner tries to get rid of this unwanted data and restore your PC to full speed. The problem is that the cleaning process is less than perfect. In particular, there is always a small risk that the registry cleaner may incorrectly remove data that is actually needed. In the worst case scenario, your PC may become unusable as a result.
That's why it's absolutely essential that you backup your registry before using a registry cleaner. For most users the easiest way to do this is to create a system checkpoint. An even better way is to use a drive-imaging program to create a snapshot of Windows, which you can use for system recovery if needed. As an added layer of protection, that may actually be more effective than System Restore, consider using the excellent ERUNT utility.
This ever-present risk of problems is why the "best" registry cleaner is the one that causes the fewest problems, rather than the one that finds the greatest number of registry errors.
Thus it is evident, a registry cleaner is - if at all - a tool reserved for the experienced user. The inexperienced may be assured that since the introduction of Windows XP, registry cleaning is no longer a crucial issue for the stability, security and performance of your system. Don't mess around with it!
