The error is a "Status Object Name Collision" . It typically means the Windows Update Trace Logger tried to start, but a session with that same name was already running. Is this serious? In most cases, no . When the Windows Update service attempts to start

The error 0xc0000035 associated with the failure to start the WindowsUpdateTraceLog session indicates a specific naming conflict within the Windows Event Tracing for Windows (ETW) subsystem. When the Windows Update service attempts to start an ETW trace session for diagnostic logging, it fails because an AutoLogger session with the same name is already registered in the registry but not active, or a stale session entry exists. This paper details the root cause, diagnostic steps, and resolution methods for this error. In plain English

: An existing trace session is already using the name WindowsUpdateTraceLog.

In plain English, this means a process (usually related to Windows Update or performance monitoring) tried to start a logging session using a name that was already in use by another active session. While it looks intimidating, it is often a benign "noise" entry that can be safely ignored if your system is otherwise running smoothly.
