Method, system and device for validating repair files and repairing corrupt software

摘要

A system and method for repairing corrupt software components of a computer system. Corrupt software is detected and repaired utilizing an automated component repair service. Repair files are downloaded from an external storage location and used to repair the corruption. The downloaded files are preferably the smallest amount of data necessary to repair the identified corruption. The process of repairing corrupt files is used in conjunction with a software updating service to resolve problems that occur when corrupt software is updated by allowing a corrupt component to be repaired and then uninstalled such that an updated component can be properly installed.

主权项

1. A method performed on a computing device that includes a processor, memory, and a component repair service, the method comprising:
determining, by the component repair service operating on the computing device, a set of corrupt files; obtaining, by the component repair service, a set of repair files that corresponds to the determined set of corrupt files, where the component repair service is further configured for validating the set of repair files in addition to determining the set of corrupt files, and where the determining and the validating each comprises:
generating, for each file that, for the determining, is in the set of corrupt files and, for the validating, is in the set of repair files, a hash of the each file, andcomparing each generated hash to a corresponding cryptographically secure hash key of an uncorrupted version of the each file; and repairing, by the component repair service based on the obtained set of repair files, a corrupt software component that corresponds to the determined set of corrupt files.
