Types of software updates

Use the Software Update task to install three types of software updates that are each associated with a particular use case.

Corrective updates
Install corrective software updates to fix a problem. In this situation, you already identified the individual updates that you must install to fix the particular problem, so you specify each by name (ID).
Recommended updates
Install software updates that are recommended by the software vendor. The Software Update task uses the vendor defined source ID to identify recommended updates.
Functional updates
Install functional software updates to support new hardware, software, or function. The Software Update task identifies the fix categories that are associated with available functional updates. You then select fix categories to install all contained updates.
