What this code can mean
An operation received data it could not use. In Windows Update this may be associated with update data or cache problems.
Possible causes to investigate
- Incomplete or damaged update data.
- Invalid configuration or servicing data.
- The failure is limited to one update or component.
Safer troubleshooting order
- Record the update and full code.
- Check storage and run the built-in troubleshooter.
- If it persists, follow current Microsoft steps for the exact code and Windows version.
Identify which data the operation rejected
Invalid data can originate from an update package, configuration, input file or another component. The same code can appear in different contexts, so use the failing operation and log to choose the repair. Do not edit the registry or reset Windows solely on the basis of this code.
Details to keep: Record the operation, complete error text, package/file name, recent changes and any built-in troubleshooter result.
Use the code with the full message, Windows version, recent changes and diagnostic evidence. Back up important files before recovery or servicing.
Before applying a code-specific fix
Windows error codes can vary by operation and version. Match the complete message, Windows build and update or driver involved, then follow the diagnostic order on this page before attempting a disruptive recovery.
