WER-SystemErrorReporting bugcheck: preserve the stop code and dump path

When Event ID 1001 says the computer rebooted from a bugcheck, the useful evidence is the exact bugcheck code, parameters and saved dump.

Applies to: Windows 11 / Windows clientReviewed: 2026-09-17

What it means in this context

Microsoft documents WER-SystemErrorReporting Event ID 1001 in reboot investigations as evidence that Windows rebooted from a bugcheck. The event can include the stop code and the MEMORY.DMP or minidump path. It confirms a kernel crash occurred but does not by itself prove which driver or hardware device caused it.

Start here
  1. Confirm the source is WER-SystemErrorReporting and preserve the full bugcheck code.
  2. Record the dump path and Report ID if present.
  3. Match the bugcheck code to the dedicated stop-code record when available.
  4. Keep the dump for deeper analysis if crashes repeat.
1

Use the stop code before changing unrelated drivers

Low risk

Why: The bugcheck family defines which parameters and subsystems are relevant.

  1. Copy the exact hexadecimal bugcheck code.
  2. Open the matching stop-code reference.
  3. Compare recent driver/hardware changes with that code’s documented context.
2

Preserve the crash dump when the cause remains unclear

Low risk

Why: A dump contains far more diagnostic context than Event ID 1001 alone.

  1. Do not delete the referenced dump while troubleshooting.
  2. If crashes repeat, use supported debugging or professional analysis rather than guessing from the event name.
Scope boundary

When not to use this record

Do not declare the named module, a random recent update or Event ID 1001 itself to be the root cause without matching crash evidence.

If it persists

Continue with the exact bugcheck record, Event Viewer timeline, Memory Diagnostic or hardware/vendor testing depending on the stop code and repeated evidence.
