Error 0xC0000096 — STATUS_PRIVILEGED_INSTRUCTION | Application Error Fix

Windows 10Windows 11Windows Server 2016Windows Server 2019Windows Server 2022

What Does 0xC0000096 Mean?

A privileged instruction was executed at user mode. The application tried to execute a CPU instruction that requires kernel-level privileges.

Real-World Causes

  1. 1Application bug causing execution of privileged CPU instructions
  2. 2Corrupted executable containing invalid machine code
  3. 3Buffer overflow redirecting execution to data interpreted as privileged instructions
  4. 4Application designed for kernel mode incorrectly running in user mode
  5. 5Code compiled for a different CPU architecture

Symptoms

  • Application crashes with privileged instruction error
  • Crash occurs at the same point consistently
  • Debug output shows the faulting instruction is a ring-0 CPU opcode
  • Event Viewer shows exception code 0xC0000096

DIY Fix

Beginner-friendly steps you can try at home

  1. 1Update the application to the latest version
  2. 2Reinstall the application to replace corrupted executables
  3. 3Run a malware scan to check for code injection
  4. 4Verify the application is intended for your CPU architecture (x86, x64, ARM64)

Advanced Fix

For experienced users and IT professionals

  1. 1Use WinDbg to disassemble the faulting instruction and identify why a privileged opcode is being executed
  2. 2Check if the crash is at a predictable address which may indicate code corruption
  3. 3Verify the executable has not been modified: check file hash against the developer's published hash
  4. 4Run the application under Application Verifier to catch memory corruption before it affects code execution

Frequently Asked Questions

What are privileged instructions?
Certain CPU instructions (like halt, I/O port access, or modifying system registers) can only run in ring 0 (kernel mode). User-mode applications run in ring 3 and cannot execute these instructions. If they try, the CPU raises an exception.
Could this be caused by malware?
Yes. Malware may attempt to execute privileged instructions as part of an exploit or rootkit installation. Run a full antivirus scan and check the application integrity if you see this error unexpectedly.
