ETW sessions are managed by the kernel and require specific file handles and memory buffers to operate. If a session is requested with a file path that is currently inaccessible or locked by another process, the Session Manager cannot initialize the logger.

To resolve the 0xc0000035 error, the existing lock on the trace log files must be released.

Windows Update utilizes the Event Tracing for Windows (ETW) infrastructure to log diagnostic information regarding the detection, download, and installation of updates.
