Abstract

Methods and systems for use in generating read-only production operating systems including at least one application for use with a target workstation are disclosed. One example method includes providing a baseline operating system based on a hardware profile of the target workstation, executing an installation script for a target application, adding at least one resource to the baseline operating system based on an error message indicating at least one resource called by the installation script is not found, and writing, at a computing device, a production operating system to a read-only media. The production operating includes the baseline operating system and the at least one resource.

Claims

1. A method of generating a read-only production operating system including at least one application for use with a target workstation, said method comprising:

providing a baseline operating system based on a hardware profile of the target workstation;

executing the baseline operating system in a virtual machine generated in a first operating system on a computing device;

executing a target application in the virtual machine and recording each resource called by a processor in the computing device while executing the target application;

generating an installation script from the recorded resources;

executing, at the computing device, the installation script for the target application;

adding at least one resource to the baseline operating system based on an error message indicating at least one resource called by the installation script is not found; and

while executing a second operating system that is different from the first operating system, writing, at the computing device, a production operating system to a read-only media, the production operating system including the baseline operating system and said at least one resource.

2. The method of claim 1, wherein executing the installation script includes executing the installation script comprising a plurality of resource calls for installing the target application to the baseline operating system.

3. The method of claim 2, wherein the installation script comprises a plurality of resource calls for configuring the target application.

4. The method of claim 3, wherein the installation script comprises a plurality of resource calls for testing the target application.

5. The method of claim 1, further comprising detecting the error message indicating the at least one resource called by the installation script is not found in the baseline operating system, the resource including at least one of a file, a registry key and an instruction.

6. The method of claim 1, further comprising downloading an installation file associated with a target application from the software publisher'"'"'s website and writing the installation files to a read-only media, while executing a first operating system.

7. The method of claim 6, wherein the first operating system is different in type than the baseline operating system.

8. The method of claim 1, further comprising creating a hardware profile for a target workstation.

9. The method of claim 1, wherein executing the baseline operating system in a virtual machine further comprises executing the baseline operating system using an enhanced write filter.

10. The method of claim 1, wherein the installation script is a first installation script and the target application is a first target application, said method further comprising executing a second installation script for a second target application;

and

wherein adding the at least one resource to the baseline operating system further comprises adding the at least one resource to the baseline operating system based on an error message indicating that the at least one resource called by at least one of the first installation script and the second installation script is not found.

11. The method of claim 1, wherein the target application includes at least one of an operating system patch application, an anti-virus application, a malware detection application, and an anti-malware application.

12. The method of claim 1, further comprising running the production operating system, from the read-only media, on a target workstation.

13. A developer workstation for generating a read-only production operating system including at least one application for use with a target workstation;

said developer workstation comprising;

a memory including a plurality of resources; and

at least one processor coupled to the memory, said at least one processor configured to;

generate, in a first operating system, a virtual machine for booting a baseline operating system, wherein the baseline operating system is configured for a target workstation and includes an enhanced write filter;

execute the baseline operating system in the virtual machine;

execute a target application in the virtual machine and record each resource called by the at least one processor while executing the target application;

generate an installation script from the recorded resources;

execute the installation script for the target application to the baseline operating system;

detect at least one error message indicating at least one resource called by the installation script and omitted from the baseline operating system;

add the at least one resource from said memory to the baseline operating system; and

while executing a second operating system that is different from the first operating system, write a production operating system to a read-only media, wherein the production operating system includes the baseline operating system and the at least one resource.

14. The system of claim 13, wherein the installation script includes program code to install and configure the target application.

15. The system of claim 13, wherein the target application includes at least one of an anti-virus application and a programming tool application.

16. The system of claim 13, wherein the resource includes at least one of a file, a registry key and an instruction.

17. A method of generating a read-only production operating system including at least one application for use with a target workstation, said method comprising:

providing a baseline operating system with an enhanced write filter based on a hardware profile of the target computing device,

(a) executing the baseline operating system on a virtual machine generated in a first operating system on a computing device;

(b) executing a target application in the virtual machine and recording each resource called by a processor in the computing device while executing the target application;

(c) generating an installation script from the recorded resources;

(d) executing, on the computing device, an installation script for a target application;

(e) detecting at least one error message indicating a resource called by the installation script and omitted from the baseline operating system, the resource including at least one of a file, a registry key and an instruction;

(f) adding the resource to the baseline operating system;

repeating steps (a) thru (f) until the installation script is executed without an error message; and

while executing a second operating system that is different from the first operating system, writing, at the computing device, a production operating system to a read-only media, the production operating system including the baseline operating system and said resource(s) added to the baseline operating system during step (f).

18. The method of claim 17, wherein the installation script includes a plurality of resource calls for installing and configuring the target application on the baseline operating system.

19. The method of claim 17, further comprising downloading an installation file associated with the target application from a website of a software publisher associated with the target application.
