A method and apparatus for virtualizing access to native resources includes a hooking mechanism, a name virtualization engine, and an operating system interface. A request to access a native resource from a process executing in the context of an isolation environment is received, the request including a virtual name for the native resource. A rule action of remap is associated with the virtual name included in the received request. A literal name for the native resource is formed, the literal name identifying a literal native resource of the same type as the requested resource. A request to access the native resource is issued, the request including the determined literal name for the native resource.

A method for isolating access by application programs to native resources provided by an operating system redirects a request for a native resource made by an application program executing on behalf of a user to an isolation environment. The isolation environment includes a user isolation scope and an application isolation scope. An instance of the requested native resource is located in the user isolation scope corresponding to the user. The request for the native resource is fulfilled using the version of the resource located in the user isolation scope. If an instance of the requested native resource is not located in the user isolation scope, the request is redirected to an application isolation scope. The request for the native resource is fulfilled using the version of the resource located in the application isolation scope. If an instance of the requested native resource is not located in the application isolation scope, the request is redirected to a system scope.

A method for virtualizing access to named system objects includes the step of receiving a request to access a system object from a process executing in the context of a user isolation scope, the request including a virtual name for the system object. A rule associated with the request is determined and a literal name for the system object is formed in response to the determined rule. A request to access the system object is issued to the operating system. The issued request including the literal name for the system object

A method for associating a file type of a file with one or more programs includes the step of receiving a request to store in a configuration store file type association information. From the request, an application program is determined that is to be associated with a file type in the configuration store. An association of the file type with a chooser tool is written to the configuration store
