Another Unit 035 was already sitting at the desk, coffee in hand, scribbling furiously.
If the error persists, reopen Command Prompt as administrator and run the DISM tool: DISM /Online /Cleanup-Image /RestoreHealth Restart your computer once the process is 100% complete.
If a corrupted or stuck update is holding the trace log hostage, clearing the SoftwareDistribution folder will force Windows to reset its update components and clear out active trace files.

"Session 'WindowsUpdateTraceLog' failed to start with the following error: 0xc0000035. Repack." Another Unit 035 was already sitting at the
To understand why this error occurs, one must first understand the component at the heart of the message: WindowsUpdateTracelog . The Windows operating system utilizes a high-performance tracing architecture known as Event Tracing for Windows (ETW). ETW allows for the logging of kernel and application events in real-time, providing developers and system engineers with a granular view of system performance and behavior.

If the error is persistent but doesn't affect performance, you can stop it from appearing in your Event Viewer. and navigate to:
Since the issue stems from an initialization conflict during startup, disabling the automatic logger thread or resetting its parameters via the Registry Editor will stop the collision. ETW allows for the logging of kernel and
In the Windows subsystem, the hex code translates directly to STATUS_OBJECT_NAME_COLLISION .

Navigate to C:\Windows\SoftwareDistribution and delete everything inside. Go back to Services and the "Windows Update" service. 4. Advanced Registry Fix
. This typically happens during system startup and is often considered a benign "timing issue" that does not necessarily mean your updates are failing. Understanding the Error : The code 0xc0000035 corresponds to STATUS_OBJECT_NAME_COLLISION For system administrators and power users
The error "Session WindowsUpdateTraceLog failed to start with the following error 0xc0000035" indicates a Windows scheduled task or service (related to Windows Update tracing) could not start because an object with the same name already exists (STATUS_OBJECT_NAME_COLLISION). This typically points to a corrupted or duplicate trace session, leftover ETW (Event Tracing for Windows) registration, or conflicting tracing state.
In the intricate ecosystem of the Windows operating system, the Event Viewer serves as the silent chronicler of the system’s health, documenting everything from successful driver loads to critical application crashes. For system administrators and power users, it is an indispensable diagnostic tool. However, it is not uncommon for the Event Viewer to reveal a litany of errors that, while seemingly urgent, have nebulous origins. Among the most persistent and confusing of these entries is the error message: "Session WindowsUpdateTracelog failed to start with the following error 0xc0000035." This error, often appearing in conjunction with the use of software "repacks" or modified installers, represents a fascinating intersection of Windows internal architecture, software licensing conflicts, and the unintended consequences of software modification. This essay explores the technical anatomy of this error, the specific role of the 0xc0000035 status code, and the contextual implications of "repacking" in the software ecosystem.
Look for a sub-folder string identifier (GUID) associated with update tracking or trace logging. Common culprits include b675ec37-bdb6-4648-bc92-f3fdc74d3ca2 .
