System error codes can occur across many locations in the system and require investigation and analysis to debug (due to their scope, descriptions for system error codes cannot be very specific), starting with the programmatic and runtime context in which the errors occurred.
System error codes are defined in WinError.h and can be returned by non-system software or by a function deep in the stack and far removed from code that is handling the error.
We've listed the system error codes in this section, organized by number. If you need more help tracking down a specific error, here are some more recommendations:
- Use the Microsoft Error Lookup Tool.
- Install the Debugging Tools for Windows, load a memory dump file, and then run the !err <code> command.
- Search the Microsoft Protocols site for the raw text or error code. For more information, see [MS-ERREF]: Windows Error Codes.
If you're searching for other errors, here are some links that might help:
- Windows Update errors - For help resolving issues with Windows Update.
- Windows activation errors - For help verifying your copy of Windows.
- Troubleshooting blue screen errors - For help discovering what caused a stop error.
- Microsoft Support - For support with a Microsoft product.
Other error codes may be generated by third party services or apps (for example, Error Code: -118 may be displayed by the Steam game service), in which case you need to contact the third party.
The following topics provide lists of system error codes defined in the WinError.h header file.
