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

Navigate to the following registry path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WMI\Autologger\WindowsUpdateTracelog In the right pane, locate the Start DWORD value.

The concept of a "collision" in software terms is akin to two people trying to sit in the same single seat simultaneously. If the WindowsUpdateTracelog session is already active—even if it is in a stalled, background, or "zombie" state—and another process attempts to initialize a new session with the same identifier, the kernel rejects the request. It rejects it not because the request is malformed, but because the namespace is already occupied. Therefore, the error does not necessarily imply that the tracing system is broken; rather, it suggests a conflict in the initialization sequence, where the system is trying to start something that the environment suggests is already started.

This error typically indicates an initialization conflict within the Windows Event Trace session management. While it rarely causes immediate system crashes, leaving it unresolved can clutter your error logs and point to underlying configuration issues with Windows Update or diagnostic tracking. Understanding Error Code 0xc0000035 It rejects it not because the request is

In these custom builds, creators often aggressively disable telemetry, remove core system files, or block the Windows Update infrastructure entirely to save space and resources.

Use the logman utility to identify and stop any duplicate sessions that are causing the collision. Open as an administrator. While it rarely causes immediate system crashes, leaving

It is likely a temporary glitch. You can safely ignore it.

When a repack installer runs, it often executes a script to disable services and background tasks that might interfere with the installation. If the script forcibly kills the Windows Update service or the specific tracing session without properly closing the handle, the system may retain a "ghost" reference to the WindowsUpdateTracelog . Alternatively, some repack scripts attempt to mimic system behaviors to check for update dependencies or to modify system files. In doing so, they might inadvertently trigger the initialization of the WindowsUpdateTracelog . In the filter dialog

The Autologger cache files or temporary installation files have become corrupted.

Press Windows + R , type eventvwr.msc , and press Enter. In the Event Viewer, expand Windows Logs and click on System . Then, click Filter Current Log... on the right side. In the filter dialog, set the Event IDs field to 2 and the Event sources field to Microsoft-Windows-Kernel-EventTracing and click OK . This will show you all relevant errors for this session.

The error code (Status Object Name Collision) typically occurs when a logging session (like WindowsUpdateTracelog or RUXIMLog ) tries to start using a name that is already in use by an active or improperly closed session.
