Abstract

A system repurposes a personal computer operating with a conventional personal computer operating system, such as Windows® operating system, into a thin client computer system without requiring that the hard drive of the personal computer be re-formatted to remove the previous operating system. The personal computer has its boot loader configuration file edited to include a call to a thin client boot loader file to execute the thin client operating system stored on the personal computer hard drive instead of the previous operating system of the personal computer. The repurposed personal computer can be returned to the previous operating system by electing to bypass the thin client operating system. As a thin client computer, the repurposed personal computer is managed from a central server and can access applications and data on remote servers instead of using the application programs on the hard drive or the capability of storing data on the personal computer hard drive.

Claims

1. A method of converting a personal computer having an initial operating system stored into a memory device on said personal computer, into a thin client computer that is operatively connected to a server computer to be centrally managed, comprising the steps of:

loading repurposing software onto said personal computer, including a thin client operating system in parallel with said initial operating system;

editing a boot file on said personal computer to insert a command to access a thin client operating system before executing commands to load said initial operating system, said initial PC operating system being interrupted and rendered inoperative when said personal computer is re-booted, said initial operating system remaining on said memory device along with application files previously stored thereon; and

by-passing said initial operating system and operating said personal computer as a thin client computer that can be managed centrally without accessing said initial operating system or said application files on said memory device.

2. The method of claim 1 further comprising the step of:

providing a elective option to boot said personal computer into said initial operating system.

3. The method of claim 2 wherein said thin client operating system is a default operating system for said personal computer.

4. The method of claim 3 wherein said editing step inserts a command into a configuration file of said initial operating system.

5. The method of claim 4 wherein said loading step stores executable code, binaries and libraries of said thin client operating system onto said memory device without erasing existing files on said memory device.

6. The method of claim 5 wherein said loading step is accomplished without requiring a partitioning of said memory device.

7. The method of claim 6 wherein said loading step is accomplished by said server computer loading files on said personal computer.

8. The method of claim 6 wherein said loading step is accomplished by directly placing said repurposing software onto said personal computer.

9. A method of extending an effective operative life of a personal computer having an initial operating system stored into a hard drive on said personal computer by converting said personal computer into a thin client computer that is operatively connected to a server computer to be centrally managed from said server computer, comprising the steps of:

storing executable code, binaries and libraries of a thin client operating system onto said hard drive without erasing existing files on said hard drive;

editing a configuration file of said initial operating system to insert a command to execute a boot sequence for said thin client operating system before executing commands to load said initial operating system, said initial PC operating system being interrupted and rendered inoperative when said personal computer is re-booted, said initial operating system being retained on said personal computer in an operative state in parallel with said thin client operating system; and

by-passing said initial operating system and operating said personal computer as a thin client computer that is centrally managed by said server computer such that said personal computer cannot access application and data files on said hard drive.

10. The method of claim 9 wherein said thin client operating system is a default operating system for said personal computer.

11. The method of claim 9 wherein said loading step is accomplished without requiring a partitioning of said memory device.

12. The method of claim 9 further comprising the step of:

providing a elective option to boot said personal computer into said initial operating system.

13. The method of claim 9 wherein said loading step is accomplished by said server computer loading files on said personal computer.

14. A method of repurposing personal computers operating under an initial PC operating system into a thin client operating system to operate as a thin client computer that that is operatively connected to a server computer to be centrally managed, comprising the steps of:

booting said personal computer using said initial PC operating system;

editing a boot loader file in said initial PC operating system to add a command to access a thin client configuration file before said personal computer is booted into said initial PC operating system, said initial PC operating system being interrupted and rendered inoperative when said personal computer is re-booted;

loading thin client executable files, said thin client configuration file, thin client binaries and thin client libraries onto a hard drive on said personal computer in parallel with said initial PC operating system without erasing any files from said initial PC operating system; and

re-booting said personal computer to convert said personal computer into a thin client computer, whereby said personal computer by-passes said initial PC operating system to operate through said thin client configuration file, making said thin client operating system the default operating system for said personal computer.
