Abstract

Examples of methods and apparatus are provided for self-provisioning of configuration for a specific-purpose local client having a windows-based embedded image with a write-filter and obviating reinstallation of an entire windows-based embedded image onto the specific-purpose local client. The apparatus may include a retrieval module of the specific-purpose local client configured to facilitate locating a repository server containing a configuration file. The retrieval module may be configured to facilitate obtaining the configuration file from the repository server while the write-filter is enabled, while obviating reinstallation of an entire windows-based embedded image onto the specific-purpose local client. The apparatus may include an apply settings module of the specific-purpose local client configured to apply a configuration change to the windows-based embedded image based on the configuration file or another configuration file.

Claims

1. An apparatus for self-provisioning of configuration for a specific-purpose local client having a windows-based embedded image with a write-filter and obviating reinstallation of an entire windows-based embedded image onto the specific-purpose local client, the apparatus comprising:

a processor; and

a memory communicatively coupled to the processor and having stored thereon computer-executable instructions that, when executed by the processor, are configured to cause the processor to;

automatically locate a repository server containing a configuration file;

automatically obtain the configuration file from the repository server while the write-filter is enabled, while obviating reinstallation of an entire windows-based embedded image onto the specific-purpose local client; and

apply, while the write-filter is enabled, a configuration change to the windows-based embedded image based on the configuration file or another configuration file;

wherein the write-filter prevents one or more changes applied to the windows-based embedded image from persisting across a reboot of the specific-purpose local client when the write-filter is enabled.

2. The apparatus of claim 1, wherein the computer-executable instructions are further configured, when executed by the processor, to cause the processor to, after each reboot of the specific-purpose local client is initiated, automatically apply the configuration change to the windows-based embedded image to allow the configuration change to appear, to a user of the specific-purpose local client, to be persistent across a reboot of the specific-purpose local client.

3. The apparatus of claim 1, wherein the computer-executable instructions are further configured, when executed by the processor, to cause the processor to, after each reboot of the specific-purpose local client is initiated, automatically facilitate locating a repository server containing a configuration file and facilitate obtaining a configuration file.

4. The apparatus of claim 1, wherein:

the write-filter comprises an exclusion list that identifies one or more of folders that are to be retained on the specific-purpose local client across a reboot of the specific-purpose local client; and

the configuration change applied to the windows-based embedded image while the write-filter is enabled is to be discarded from the specific-purpose local client across a reboot of the specific-purpose local client, after a reboot of the specific-purpose local client is initiated.

5. The apparatus of claim 1, wherein the configuration change comprises one or more of the following:

a configuration change to a remote desktop connection, a configuration change to a device of the specific-purpose local client, or a configuration change to the operating system of the specific-purpose local client.

6. The apparatus of claim 1, wherein the computer-executable instructions are further configured, when executed by the processor, to cause the processor to, while the write-filter is enabled, save the configuration file into a storage area that is to be retained on the specific-purpose local client across a reboot of the specific-purpose local client.

7. The apparatus of claim 1, wherein the computer-executable instructions are further configured, when executed by the processor, to cause the processor to automatically apply the configuration change after a reboot of the specific-purpose local client is initiated and without a user'"'"'s intervention, the configuration change based on the configuration file saved in a storage area that is retained on the specific-purpose local client across a reboot of the specific-purpose local client, such that the configuration change appears to the user of the specific-purpose local client to be persistent across a reboot of the specific-purpose local client.

8. The apparatus of claim 1, wherein the configuration file comprises an XML configuration file.

9. The apparatus of claim 1, wherein the computer-executable instructions are further configured, when executed by the processor, to cause the processor to, obtain address information of the repository server using at least one of a dynamic host configuration protocol (DHCP) or a domain name system (DNS).

10. The apparatus of claim 1, wherein the computer-executable instructions are further configured, when executed by the processor, to cause the processor to, obtain address information of the repository server from a local registry of the specific-purpose local client.

11. The apparatus of claim 1, wherein the another configuration file is a default configuration file saved in a storage area that is retained on the specific-purpose local client across a reboot of the specific-purpose local client.

12. The apparatus of claim 1, the computer-executable instructions are further configured, when executed by the processor, to cause the processor to:

determine whether to reset a previous state of the windows- based embedded image based on the configuration file;

apply a default configuration to the windows-based embedded image and apply the configuration change to the windows-based embedded image based on the configuration file after the default configuration is applied, if the processor determines that the previous state is to be reset; and

apply the configuration change to the windows-based embedded image based on the configuration file while disallowing the default configuration from being applied to the windows-based embedded image, if the processor determines that the previous state is not to be reset.

13. The apparatus of claim 1, wherein the windows-based embedded image supports a graphical user interface and comprises an operating system and one or more applications dedicated to the specific purpose.

14. The apparatus of claim 1, wherein the computer-executable instructions are further configured, when executed by the processor, to cause the processor to:

automatically re-obtain the configuration file from the repository server or the another configuration file from a storage area that is retained on the specific-purpose local client across a reboot of the specific-purpose local client; and

automatically re-apply the configuration change associated with the configuration file or the another configuration file.

15. A method for self-provisioning of configuration for a specific-purpose local client having a windows-based embedded image with a write-filter and obviating reinstallation of an entire windows-based embedded image onto the specific-purpose local client, the method comprising:

automatically locating, by a processor of the specific-purpose local client, a repository server containing a configuration file;

automatically obtaining, at the specific-purpose local client, the configuration file from the repository server while the write-filter is enabled, while obviating reinstallation of an entire windows-based embedded image onto the specific-purpose local client; and

applying, by a processor of the specific-purpose local client, a configuration change to the windows-based embedded image based on the configuration file or another configuration file while the write-filter is enabled;

wherein the write-filter prevents one or more changes applied to the windows-based embedded image from persisting across a reboot of the specific-purpose local client when the write-filter is enabled.

16. The method of claim 15, wherein the windows-based embedded image supports a graphical user interface and comprises an operating system and one or more applications dedicated to the specific purpose.

17. A non-transitory machine-readable storage medium encoded with instructions executable by a processing system to perform a method for self-provisioning of configuration for a specific-purpose local client having a windows-based embedded image with a write-filter and obviating reinstallation of an entire windows-based embedded image onto the specific-purpose local client, the instructions comprising code for:

automatically locating a repository server containing a configuration file;

automatically obtaining, at the specific-purpose local client, the configuration file from the repository server while the write-filter is enabled, while obviating reinstallation of an entire windows-based embedded image onto the specific-purpose local client; and

applying, while the write-filter is enabled, a configuration change to the windows-based embedded image based on the configuration file or another configuration file;

wherein the write-filter prevents one or more changes applied to the windows-based embedded image from persisting across a reboot of the specific-purpose local client when the write-filter is enabled.

18. The non-transitory machine-readable storage medium of claim 17, wherein the windows-based embedded image supports a graphical user interface and comprises an operating system and one or more applications dedicated to the specific purpose.
