A self-heal tool performs self-healing tasks such as diagnostic and repair tasks at the computer host to resolve a user problem. The self-heal tool includes an instruction file and a self-heal engine which executes instructions in the instruction file. The self-healing tasks can therefore be defined independently of the engine. Further, self-healing tasks can be added, deleted or modified without replacing the entire instruction file. The self-healing tasks can involve file input-output, registry-related repairs and operating system-related repairs, for instance. The instruction file can be provided as an XML file having a hierarchy of nodes, including issue nodes that identify a diagnostic and/or repair issue, intermediate nodes referenced by the issue nodes, and task nodes that are referenced by the intermediate nodes, and that define the self-healing tasks. The data structure facilitates updates and code sharing by the issue nodes and/or intermediate nodes.
