PROFILER_CONFIGURATION_ILLEGAL
Illegal kernel profiler configuration for PROFILER_CONFIGURATION_ILLEGAL
PROFILER_CONFIGURATION_ILLEGAL is bug check code 0x0000017B. This bug check points at kernel profiling or tracing configuration that the system rejected as unsafe or inconsistent. It should be read as a configuration and instrumentation problem, not as a normal application performance issue.
How to read it in a dump for PROFILER_CONFIGURATION_ILLEGAL
- Identify active kernel profilers, ETW sessions, sampling sources, and performance counter configuration.
- The failure can be caused by unsupported sampling mode, bad buffer setup, or incompatible profiling flags.
- Third-party profilers and security tools can be involved if they program low-level counters.
What to check for PROFILER_CONFIGURATION_ILLEGAL
- Disable or update the profiler or monitoring driver that is active in the dump.
- Check ETW/perf counter configuration and recent tracing changes.
- Reproduce with symbols and verifier if a driver programs processor performance facilities directly.

Dump evidence for PROFILER_CONFIGURATION_ILLEGAL
For PROFILER_CONFIGURATION_ILLEGAL, preserve the complete dump, the four bug-check parameters, the exact Windows build, loaded-module list, and the event timeline immediately before the stop. AllStat summarizes the condition as “PROFILER_CONFIGURATION_ILLEGAL”; that sentence identifies the failure class, while the parameters and stack determine which object, driver, processor, or subsystem instance was involved.
Analysis order for PROFILER_CONFIGURATION_ILLEGAL
- Run WinDbg
!analyze -v, then inspect the documented meaning of each PROFILER_CONFIGURATION_ILLEGAL parameter instead of relying only on the probably-caused-by line. - For PROFILER_CONFIGURATION_ILLEGAL, find the earliest abnormal event: driver update, firmware change, device reset, storage error, verifier report, resource exhaustion, or application hang connected with profiler / configuration / illegal.
- For PROFILER_CONFIGURATION_ILLEGAL, keep third-party filter, security, storage, graphics, and virtualization drivers in the module inventory; removing evidence before dump analysis can obscure the responsible path.
Do not repeatedly reboot a machine affected by PROFILER_CONFIGURATION_ILLEGAL before collecting the dump and event logs. For PROFILER_CONFIGURATION_ILLEGAL, recovery actions should follow the component identified by the stack and parameters, not merely the symbolic stop-code name.
