How to delete a registry file?
Never ever go into the Registry and start deleting things unless you know exactly what you are doing. For a start you probably wouldn’t be able to find it as there are thousands of files and settings. As you have deleted the program more than likely you have now what they call an “Empty Registry Key” so I suggest you go to ► http://www.piriform.com/ and then download CCleaner. This small free program will find all the empty Registry keys and delete them.
