When running psort against a log2timeline-generated plaso file, message strings from the a custom winevt-rc.db database are applied only to a minority of Event Logs records, despite multiple messages and logs in the database which should apply. The custom database was generated from the same language and OS version as the host where the Event Logs were captured from.
Upon further inspection, I noticed that the custom winevt-rc.db I generated from a fresh Windows 11 install (using instructions from here: http://blog.kiddaland.net/2015/04/windows-event-log-message-strings.html) had prefixed 0xb instead of 0x0 to the majority of message_identifier fields.
A good example is the source "Microsoft-Windows-TerminalServices-LocalSessionManager". The entries in winevt-rc.db look like this:
If I manually change line 22 to 0x0 from 0xb, the Message String is correctly displayed in the psort output for that event:
Have I done something wrong in generating winevt-rc.db or is this a bug?
Please provide the source data you used when you experienced the problem. For publicly available data please provide a URL or path of the source data:
Fresh Windows 11 ISO from Microsoft > create Hyper-V VM > Run winevt-kb/extract.py against the image
The method you used to install Plaso:
Installed from [l2tbinaries][https://github.com/log2timeline/l2tbinaries] main branch
Expected behavior:
Message Strings are generated for Event Logs, based on message_identifier mappings

To Reproduce:
The versions used:
winevt-kb latest, from https://github.com/libyal/winevt-kb
dfvfs latest, from https://github.com/log2timeline/dfvfs
The operating system you are running Plaso on (Not the operating system of the image/files you're trying to analyze):
Ubuntu 24.04
Steps to reproduce the behavior including command line and arguments and output:
Follow the instructions to build your own winevt-rc.db here, running against a fresh Windows 11 installation disk image: http://blog.kiddaland.net/2015/04/windows-event-log-message-strings.html#:~:text=How%20to%20build%20your%20own%20winevt%2Drc.db
