Techniques for observing user operations and recognizing a current user of a computer based on those operations. Characteristics of observed user operations are compared to characteristics of operations performed by known users, such as those users with existing user profiles. The current user may be recognized as a user having a known user profile or a new user, for which information on user interests or other profile information may be stored. The profile of the current user may be used to customize presentation of services according to preferences for the current user. Components that collect information on user interactions may be incorporated in an operating system of the computer so that user interactions with both the operating system and applications that access operating system facilities may be used to recognize a user. Customization of the operating system or other components based on inferred user recognition may improve the user experience.
