Note The registry contains information that Windows continually references during operation such as profiles for each user the applications installed on the computer and the types of documents that each can create property sheet settings for folders and application icons what hardware exists on the system and the ports that are being used. Optimize looks for specific registry keys that can slow the computer s performance. These are typically invalid keys containing information about COM and ActiveX objects. These objects are parts of programs and when you remove the programs these keys sometimes still exist. Optimize safely removes these keys if the COM object no longer exists. Areas of the registry where Optimize looks for the invalid keys are Invalid Class IDs CLSID This is a universally unique identifier UUID that identifies a COM component. Each COM component has its CLSID in the Windows registry so that it can be loaded by other applications. Invalid Program Identifiers ProgID A programmatic identifier is a registry entry that identifies a COM component and can be associated with a CLSID. Invalid Type Libraries TypeLib This identifies a type library file contain standard descriptions of data types modules and interfaces that can be used to fully expose objects with ActiveX technology.
