Hi,

event tracing files, for example produced by wusa.exe log parameter, are binary files. The powershell command let Get-WinEvent couldn’t open it but Windows Eventviewer is able to read those files.
There is also an option to convert ETL files.

The command line utility tracerpt.exe could convert it in different formats:
– CSV
– Evtx (Eventlog format, then Get-WinEvent can read this)
– XML

This converts a ETL file into a csv file

PS D:\> tracerpt.exe kb5055518.log.etl -of csv -o kb5055518.csv

or to an evtx file

PS D:\> tracerpt.exe kb5055518.log.etl -of evtx -o kb5055518.evtx
PS D:\> Get-WinEvent -Path kb5055518.evtx
