Microsoftwindowswindowsupdateruximlog Failed To Start Patched

The error message “Microsoft Windows Windows Update Ruximlog failed to start patched” typically appears when a Windows Update component (possibly a misnamed or corrupted service/file related to ruximlog or update logging) fails to initialize. This can prevent Windows Update from running correctly and may indicate system file corruption, registry issues, or a failed update patch.

Note: ruximlog is not a standard Windows component. This error often stems from:

The event log entry involving microsoft-windows-windowsupdate-ruximlog (often appearing as Event ID 7000 or 7023 in the System log) typically indicates that a specific Windows Update component failed to initialize. The presence of the keyword "patched" in your query suggests this error is appearing in the context of a recent Windows Update, or alternatively, it is a user's note indicating they attempted a manual fix.

This issue is generally benign but can be a symptom of a corrupted Windows Update stack, permission issues within the WinSxS store, or a stuck "Interactive Session" handler.

Run:

sfc /scannow

Then:

DISM /Online /Cleanup-Image /RestoreHealth

If ruximlog remains stubborn, manually reset the entire Windows Update pipeline.

Step 1: Stop critical services Open Admin Command Prompt and run:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver

Step 2: Rename the SoftwareDistribution and Catroot2 folders These hold update logs and history, possibly including the corrupt ruximlog reference. Note: ruximlog is not a standard Windows component

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old

Step 3: Restart services

net start wuauserv
net start cryptSvc
net start bits
net start msiserver

Step 4: Re-attempt Windows Update Go to Settings > Windows Update and retry. Windows will rebuild the ruximlog logging environment from scratch.

If SFC doesn't fix the issue, try running a DISM scan.
