To Start With The Following Error 0xc0000035 Repack — Session Windowsupdatetracelog Failed

"Session 'WindowsUpdateTraceLog' failed to start with the following error: 0xc0000035. Repack."

The error is a Kernel Event Tracing issue that occurs when Windows attempts to start a logging session (like WindowsUpdateTraceLog or RUXIMLog ) but fails because an object with the same name already exists. In technical terms, it is a STATUS_OBJECT_NAME_COLLISION .

Navigate to C:\Windows\SoftwareDistribution and delete all contents. Restart the service: net start wuauserv 4. Advanced: Registry Modification

Then reboot – the trace session should be recreated automatically when needed.
