0 is a status or completion value, not necessarily a failure. Microsoft’s system-code table describes this value as: “The operation completed successfully.”
Completion or status value
Read the exact screen and operation before selecting a repair. This page does not run commands or collect files, keys or logs.
What this value means
Microsoft’s system-code table describes this value as: “The operation completed successfully.”
ERROR_SUCCESS is a Win32 system result, usually returned to an application or API caller. It is not a Windows blue-screen code or a diagnosis of the whole PC.
| Code | 0 |
|---|---|
| Hex form | 0x0 |
| Symbol | ERROR_SUCCESS |
| Windows family | Win32 system codes |
| Source level | Microsoft code and symbol entry |
Safe next steps
- For 0 (ERROR_SUCCESS), check whether the operation actually finished and whether the application asks for a restart or another step.
- Save work before a required restart and confirm the result in the application or Windows update history.
- Do not run a repair merely because a status value contains the word “error” in its symbolic name.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
What this code cannot prove
The source establishes the identifier and reference meaning. It does not establish the cause on your specific PC.
A success or status code needs no repair on its own. Act only if the operation or app actually failed.
