| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 2 | 0 |
Determines which errors appear as pop-up error messages that interrupt the user. ErrorMode is a system-level control of pop-up error messages from system processes and applications. Applications determine which of their errors can appear as pop-ups. ErrorMode can suppress only those pop-ups that applications can display.
| Value | Meaning |
|---|---|
| 0 | All errors appear in pop-ups. |
| 1 | Errors from system processes do not appear in pop-ups. Application errors still appear in pop-ups. |
| 2 | Neither application errors nor system process errors appear in pop-ups. This value is designed for unattended computers. |
Note
This value does not affect error logging; all messages that appear as pop-ups are also written to the event log.
