Basically, there are two different kinds of registry editing tools. The first type is the Windows built in registry editor which is called”regedit.” Regedit is found by clicking on the start menu and then typing regedit into the run box.
there are other such tools made for specifically for Microsoft certified professionals to ue for changing entries in the registry. These tolls are nothing more than regedit with a few more bells and whistles. 
However, regedit or any of 
these tools should not be used by anyone who is not thoroughly familiar with Windows registries. This is because entering the run thing into registry or deleting anything could make the operating system unusable. What is worse is this damage may be irreversible!
The second type of registry editing tool is highly recommended. It is a registry cleaner. A registry cleaner can do anything a human could in a fraction of the time with no risk involved. However, make sure to use the right one because the using the wrong registry cleaner is a waste of time. The right one will clear out all computer errors and get your computer’s speed back up to its highest potential.
Even folks who have worked on computers a long time prefer using a registry cleaner to making changes to the registry manually. The reason for this is it is just so much easier to run a software program than it is to perform the tedious tasks that are involved when working on a registry manually! This is not to even mention the pressure involved when you know if you do mess-up you may make the operating system unworkable. This is the type of pressure one used to feel before registry cleaning software was developed.
Then there is the time aspect. It cost a pretty good amount to have a technician work inside your computer’s registry for a couple hour whereas running a registry cleaner is not at all expensive. In fact, just getting a scan with a top notch registry cleaner to find if there is corruption in the registry is usually free.
