Safe next steps

  1. For 0x0000018D (SECURE_FAULT_UNHANDLED), record the exact stop code and parameters. Microsoft’s debugger reference may describe a kernel condition rather than a consumer fix.
  2. If crashes repeat, inspect the dump locally with official WinDbg and compare its parameters with this code’s Microsoft page.
  3. Do not enable Driver Verifier or change firmware as a generic first step; ask qualified support if the PC cannot start.

After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.

What this code cannot prove

The source establishes the identifier and reference meaning. It does not establish the cause on your specific PC.
