Abstract

Systems and methods for running add-on components in virtual environments are described. An add-on component can be executed in a virtual environment by setting up a communication link between a component proxy in the host operating system and a server process running in the virtual environment. The server process executes the add-on component based on commands forwarded by the component proxy forwards the commands from the operating system.

Claims

1. A system implemented on one or more computing devices comprising:

an operating system;

a component proxy included in the operating system;

a virtual environment that communicates with the component proxy;

a component server process in the virtual environment;

one or more virtual applications in the virtual environment; and

one or more add-on components that are associated with the one or more virtual applications, wherein the component server process receives commands forwarded by the component proxy and executes the add-on components.

2. The system of claim 1, wherein the component proxy is registered with the operating system for one or more of the add-on components.

3. The system of claim 2, wherein the registration is performed when the virtual environment is simulated on the one or more computing devices.

4. The system of claim 1, wherein the operating system invokes the component proxy to access the one or more add-on components.

5. The system of claim 1, wherein the component proxy checks for the correct virtual environment in which the component server process is launched, and connects to a server running in an appropriate virtual environment if the component proxy is registered with enough information.

6. The system of claim 1, wherein the component proxy accesses a manifest of virtual environments to determine components supported by the component proxy without launching a server.

7. The system of claim 1, wherein the one or more add-on components includes a shell extension.

8. A computer-readable medium having computer-executable components comprising:

a component proxy;

a virtual environment that communicates with the component proxy;

a component server process included in the virtual environment; and

an add-on component in the component server process, wherein the add-on provides functionality to an application.

9. The computer-readable medium of claim 8, wherein the virtual environment is simulated by an application on a server component.

10. The computer-readable medium of claim 8, further comprising a server component that includes information as to interaction of the add-on component with an operating system.

11. The computer-readable medium of claim 10, wherein the server component logs one or more of the following:

registry settings, files, application variables, and operating system variables.

12. The computer-readable medium of claim 8, further comprising a virtual application of an application resident on a server component.

13. A method of running add-on components in a virtual environment comprising:

invoking a component proxy corresponding to an add-on component, wherein the add-on component provides functionalities;

associating with the virtual environment;

determining if the virtual environment is the correct virtual environment; and

launching a component server process if the virtual environment is determined to be correct.

14. The method of claim 13, wherein an application program interface is used in the associating.

15. The method of claim 13, wherein the determining includes checking whether the virtual environment includes the corresponding add-on component.

16. The method of claim 13, wherein the launching is performed after validating that the add-on component is hosted in the virtual environment.

17. The method of claim 13 further comprising finding a correct virtual environment if the determining finds that the virtual environment is not correct, and connecting to a server running in an appropriate virtual environment if the component proxy is registered with enough information.

18. The method of claim 13, wherein the component proxy accesses a manifest of virtual environments to determine components supported by the component proxy without launching a server.

19. The method of claim 13 further comprising creating an instance of the add-on component corresponding to component proxy in the virtual environment.

20. The method of claim 15 further comprising forwarding commands from the component proxy to the component server process and to the add-on component.
