When you delete a named program the empty compartment will remain and becomes known as an uninstall entry,if you visualize the CPU as a large box which has numerous little compartments inside it and each one is a named program.You will increase computer performance because the CPU will speed up if you regularly clear out the empty named program compartments using a registry cleaner.However,if you choose not to clean out the registry on a regular basis,the CPU becomes overcrowded and it takes longer to find the named program compartment you want to use and you are unlikely to increase computer performance.The named compartments which are uninstall entries can distract the CPU when you instruct it to open or use a program.The CPU may go to any empty compartment first if there is any similarity between the deleted program and a current program. So the response from the current program is delayed and it becomes a vicious circle. The more empty compartments the CPU visits the slower the response from current programs and you will be unable to increase computer performance until the uninstall entries are removed completely.Programs which control your email, internet access and other packages, services you may use on a daily basis become sluggish and freeze or in some cases cause your system to crash completely.
