INTERRUPT_UNWIND_ATTEMPTED

Invalid unwind through interrupt context

INTERRUPT_UNWIND_ATTEMPTED is bug check code 0x0000003C. This code points at exception/unwind logic interacting with interrupt or trap state. It is typically about corrupted control-flow state, a bad trap frame, or code attempting to unwind through a context that cannot be unwound normally.

How to read it in a dump

Inspect interrupt/trap frames and the processor context saved in the dump.
The stack may be misleading if the unwind metadata is already corrupted.
Hardware interrupt handlers, DPCs, and low-level drivers are important suspects when present.

What to check

Analyze trap frames and processor state in WinDbg.
Check low-level drivers, filter hooks, and recent security or instrumentation software.
Consider memory corruption if the interrupt stack or saved context is damaged.
