I have found that even though most computers have a built in system that defragments the computer’s drive, an alternative process is usually better.  The best registry cleaner I came across will do this process as well as many other helpful ones, using much less of your system’s capability.  These processes can be very time consuming, and you do not want to spend all day trying to get your computer running right.  The use of a third party software can be a great way to do a superior job on your PC.  I would recommend it to anyone that needs to save some time waiting for their PC.
