INVALID_REGION_OR_SEGMENT
The INVALID_REGION_OR_SEGMENT bug check has a value of 0x00000099. This bug check indicates that ExInitializeRegion or ExInterlockedExtendRegion was called with an invalid set of parameters.
INVALID_REGION_OR_SEGMENT Parameters
None
Dump evidence
Preserve the complete dump, the four bug-check parameters, the exact Windows build, loaded-module list, and the event timeline immediately before the stop.
Analysis order
- Run WinDbg
!analyze -v, then inspect the documented meaning of each parameter instead of relying only on the probably-caused-by line. - Find the earliest abnormal event preceding the stop: driver update, firmware change, device reset, storage error, verifier report, resource exhaustion, or application hang.
- Keep third-party filter, security, storage, graphics, and virtualization drivers in the module inventory; removing evidence before dump analysis can obscure the responsible path.
Distinctive failure boundary
This result identifies invalid memory region or segment state. Inspect the virtual-address region, section or segment object, VAD/PTE state, and the operation that changed the mapping. Corruption here concerns memory-manager bookkeeping, not an ordinary invalid user handle.
Separating the result from neighboring bug checks
Compare mapping creation, protection changes, truncation, image loading, and teardown around the address named by the dump parameters. Preserve the original dump and use the documented parameters and stack to verify this distinction before changing drivers or platform configuration.
