The error "Microsoft.Windows.WindowsUpdate.RUXIMLog failed to start" often occurs when the Windows Update logging session is already in use or corrupted, frequently appearing in the Event Viewer with Event ID 2. This log is part of the Reusable UX Integration Manager (RUXIM), which manages update components and health. Immediate Solutions
- The Nuclear Option: Run the Windows Update Troubleshooter (Settings > System > Troubleshoot > Other troubleshooters). Surprisingly, it works for roughly 40% of cases, as it resets the Update service permissions.
- The Registry Scalpel: Navigate to
HKLM\SYSTEM\CurrentControlSet\Services\RuximLog and delete the key entirely. Reboot. Windows will regenerate it cleanly on the next update check. (Back up your registry first—this is not for the faint of heart.)
- The Silent Treatment: Use
Autoruns or Services.msc to set the Ruximlog service to "Manual" instead of "Automatic." It will still run when needed but stop trying to launch at boot, suppressing the error.
Deleting the specific session entry can force Windows to recreate it correctly upon restart , and hit Enter. Navigate to:
In the Admin Command Prompt, navigate to the RUXIM directory (usually found within C:\Windows\System32\).
