Description

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.

This value does not affect error logging; all messages that appear as pop-ups are also written to the event log.
