Event ID 1000

Application Error: application or service crash record

Preserve the faulting application, module and exception code and correlate repeated Event 1000 entries with Windows Error Reporting Event 1001.

Applies to: Windows clientReviewed: 2026-09-17

What it means in this context

Microsoft’s current application/service crash guidance says repeated Event ID 1000 together with WER Event ID 1001 indicates crashing behavior and can identify the faulting application/module context. The event is evidence for a crash signature, not proof that the named module is independently defective.

Start here
  1. Record the exact crash timestamp.
  2. Preserve the faulting application, module and exception code.
  3. Check for a matching Windows Error Reporting Event ID 1001.
  4. Compare whether the same crash signature repeats.

Use repeated crash signature and ownership to choose the repair path

Low risk

Why: First-party and third-party processes need different remediation and a one-off event can be unrelated noise.

  1. Confirm the same process/module fails repeatedly.
  2. Check Reliability Monitor and recent app/driver changes.
  3. Use the owning app/vendor repair path when the crash is third-party.
  4. Collect a dump only when the repeated crash cannot be explained by normal repair evidence.
Scope boundary

When not to use this record

Do not reinstall Windows or replace hardware solely because Event ID 1000 exists.

If it persists

Use Event ID 1001/WER details, Reliability Monitor and application/service-specific repair; use stop-code dump analysis if Windows itself crashes.
