What this value means
The local Windows en-US message table describes this value as: “Driver Verifier Volatile settings cannot be set when CFG and IO are enabled.”
ERROR_VRF_CFG_ENABLED 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 | 1183 |

Safe next steps
- For 1183 (ERROR_VRF_CFG_ENABLED), record the exact Driver Verifier or debugger operation and the settings named by the message.
- Compare the settings with Microsoft’s debugging guidance for the test machine before changing verification options.
- Driver Verifier is an advanced testing tool; do not enable or alter it as a casual consumer repair.
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
This wording came from the local Windows en-US system message table. The symbolic name is from the source dataset’s historical Boost mapping; a matching current Microsoft web pair was not found in the checked lists. Verify the exact number and applicability on the affected device.
If the result differs from the documented message or a repair could remove data, stop and use the official source or vendor support.
