What this value means
Microsoft’s system-code table describes this value as: “The code segment cannot be greater than or equal to 64K.”
ERROR_RING2SEG_MUST_BE_MOVABLE 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 | 200 |
|---|---|
| Hex form | 0xC8 |
| Symbol | ERROR_RING2SEG_MUST_BE_MOVABLE |
| Windows family | Win32 system codes |
| Source level | Microsoft code and symbol entry |
Safe next steps
- For 200 (ERROR_RING2SEG_MUST_BE_MOVABLE), identify the application and precise action that returned the value. Win32 system codes can be propagated from a deeper component.
- Read the full application message and related logs; use the publisher’s support documentation for that operation.
- A number alone does not justify replacing hardware, editing the registry, or reinstalling Windows.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
