Windows Event ID 1000 — Application Error
Logged by the Application Error Reporting service when an application crashes with an unhandled exception.
Why It Matters
Repeated crashes of the same application indicate bugs, compatibility issues, or deliberate interference. Crashes of security tools (AV engines, EDR agents) may indicate tampering.
Key Fields
Investigation Tips
- 1.Persistent crashes of security tools warrant investigation for deliberate process termination.
- 2.Crashes after software updates are often compatibility issues — check the update timeline.
