Log decoder
Paste part of a log, or open a log file, and see every error code in it, how often it appears and what it means. It finds hex codes (0x80070005, 80070005), signed decimals,
Error 1603 style numbers, and symbol names such as ERROR_ACCESS_DENIED. CBS.log, WindowsUpdate.log, Windows Installer logs and event text all work.
