For those who cannot abide the red "X" in Event Viewer, a few community-sourced fixes have emerged:
Some malware creates fake services named like Windows components. “Ruxim” is suspicious — possibly from a coin miner or backdoor that failed to load properly. microsoftwindowswindowsupdateruximlog failed to start full
RuximLog does appear in official Microsoft documentation. For those who cannot abide the red "X"
I closed the ticket. The cold coffee was finally thrown away. The machine was clean, its digital ghosts exorcised, running smoothly on the updated code that had long since forgotten the name RUXIMLog . It was a small victory, invisible to the user, but in the world of systems architecture, silence is the loudest sound of success. I closed the ticket

Observed symptoms
Here is the tragedy of the Windows Servicing Stack: It is optimistic. It assumes success. When the rollback triggered (or failed to trigger fully), the Registry key for the service remained, a tombstone marking where the update died. The actual RUXIMLog.dll file, however, was never committed to the disk, or was cleaned up by a subsequent maintenance task that deemed it orphaned debris.
