Abstract

Software update techniques are described. In at least one implementation, updates are filtered based on criticality to operation of one or more items of software. A plurality of identities are published to a plurality of computing devices, each for a respective one of the updates that are filtered as being critical to the operation of the one or more items of software. The updates that are not filtered as being critical to the operation of the one or more items of software are made available via polling.

Claims

1. A method comprising:

detecting a request at a computing device to initiate execution of software;

ascertaining an identity that indicates a unique name and version of the software, and for one or more available updates of the software, the unique name indicating specific functionality incorporated within the one or more available updates and the version of the software including a functionality version that describes features of the software and a servicing version which indicates compatible bug fixes including security fixes that were installed for the software;

comparing the ascertained identity of the software with one or more published identities of the one or more available updates that are pre-filtered as involving updates to respective software operations of the computing device, the published identities being pre-cached at the computing device to determine whether one or more of the updates are available for the software and are critical updates to the software of the computing device;

when execution of the software is initiated, and responsive to a determination that the software is not current and that the one or more updates are available for the software;

blocking execution of the software on the computing device and updating the software while execution of the software is blocked responsive to a determination that the one or more available updates are critical to the operation of the computing device; and

permitting execution of the software on the computing device while the software is not current and while updating the software via polling responsive to a determination that the one or more available updates are not critical to the operation of the computing device; and

permitting execution of the software on the computing device when the identity of the software does not correspond to the one or more published identities or when the software is current.

2. A method as described in claim 1, wherein:

each of the published identities correspond to at least one said update; and

the at least one said update is not available locally on the computing device when the comparison is performed.

3. A method as described in claim 1, wherein each of the published identities correspond to at least one said available update that is critical to the operation of the computing device.

4. A method as described in claim 3, further comprising polling for at least one said available update that is not critical to the operation of the computing device and is not referenced by the one or more published said identities.

5. A method as described in claim 3, wherein the published identities correspond to one or more security updates.

6. A method as described in claim 1, wherein the ascertaining is performed by checking a manifest that is included as a part of the software.

7. A method as described in claim 1, wherein the ascertaining is performed by checking a manifest that includes identities of a plurality of software that is installed on the computing device.

8. A system comprising:

an operating system configured to detect a request at a computing device to initiate execution of software; and

an update manager module implemented at least partially in hardware, the update manager module configured to perform operation comprising;

ascertaining an identity that indicates a unique name and version of the software, and for one or more available updates of the software, the unique name indicating specific functionality incorporated within the one or more available updates and the version of the software including a functionality version that describes features of the software and a servicing version which indicates compatible bug fixes including security fixes that were installed for the software;

comparing the ascertained identity of the software with one or more published identities of the one or more available updates that are pre-filtered as involving updates to respective software operations of the computing device, the published identities being pre-cached at the computing device to determine whether one or more of the updates are available for the software and are critical updates to the software of the computing device;

when execution of the software is initiated, and responsive to a determination that the software is not current and that the one or more updates are available for the software;

blocking execution of the software on the computing device and updating the software while execution of the software is blocked responsive to a determination that the one or more available updates are critical to the operation of the computing device; and

permitting execution of the software on the computing device while the software is not current and while updating the software via polling responsive to a determination that the one or more available updates are not critical to the operation of the computing device; and

permitting execution of the software on the computing device when the identity of the software does not correspond to the one or more published identities or when the software is current.

9. A system as described in claim 8, wherein the one ore more published identities exclude the one or more available updates that are not critical to the operation of the computing device.

10. A system as described in claim 8, wherein the one or more published identities are published to a plurality of computing devices regardless of whether a respective said computing device includes software that corresponds to the one or more published identities.

11. A system as described in claim 10, wherein the one or more published identities are configured to cause the plurality of computing devices that include software that is not current, according to a respective said identity, to block execution on the computing device of the software corresponding to the respective said identity.

12. A system as described in claim 10, wherein the one or more published identities are configured to cause the plurality of computing devices that include software that is not current, according to a respective said identity, to install a respective said available update.

13. A system as described in claim 10, wherein the operations that the update manager module is configured to perform further comprise polling for at least one said available update that is not critical to the operation of the computing device and is not referenced by the one or more published said identities.

14. A system as described in claim 10, wherein the ascertaining is performed by checking a manifest that is included as a part of the software.

15. A system as described in claim 10, wherein the ascertaining is performed by checking a manifest that includes identities of a plurality of software that is installed on the computing device.

16. One or more computer-readable memory devices including instructions that are executable by a computing device to perform operations comprising:

detecting a request at the computing device to initiate execution of software;

ascertaining an identity that indicates a unique name and version of the software and for one or more available updates of the software, the unique name indicating specific functionality incorporated within the one or more available updates and the version of the software including a functionality version that describes features of the software and servicing version which indicates compatible bug fixes including security fixes that were installed for the software;

comparing the ascertained identity of the software with one or more published identities of the one or more of the available updates that are pre-filtered as involving updating of respective software operations of the computer device, the published identities are pre-cached at the computing device to determine whether one or more of the updates are available for the software and whether are critical updates to the software of the computing device;

when execution of the software is initiated, and responsive to a determination that the software is not current and that the one or more updates are available for the software;

blocking execution of the software on the computing device and updating the software while execution of the software is blocked responsive to a determination that the one or more of the available updates software is critical to the operation of the computing device;

permitting execution of the software on the computing device while the software is not current responsive and while updating the software via polling responsive to a determination that the one or more available updates are not critical to the operation of the computing device; and

permitting execution of the software on the computing device when the identity of the software does not correspond to the one or more published identities or when the software is current.

17. One or more computer-readable memory devices as described in claim 16, wherein each of the published identities correspond to at least one said available update that is critical to the operation of the computing device.

18. One or more computer-readable memory devices as described in claim 16, wherein the software is an application, component of an operating system provided by the computing device or a plug-in module.

19. One or more computer-readable memory devices as described in claim 16, wherein the published identities correspond to the one or more available updates that relate to security.
