Livestatus

The hexadecimal result codes the Windows Update client returns when a scan, download or install does not finish. They reach the event log long before the update history screen explains anything.

This table decodes 29 codes.

SparkLogs decodes these codes on every event that carries one, regardless of feed.

How to read this

Codes are listed in numeric order. Windows publishes no constant for this space, so Name is the short label SparkLogs puts on the event, and it is what a question groups by. The last column is our one-line summary of what the code means in plain words.
