Finding subtle programming errors.
Application Verifier is a runtime verification tool for native code that assists in finding subtle programming errors that can be difficult to identify with normal application testing.

Application Verifier is designed specifically to Detect and help debug memory corruptions and critical security vulnerabilities.
This is achieved by monitoring a native applications interaction with the Windows operating system, profiling its use of objects, the registry, the file system, and Win32 APIs (including heaps, handles, Locks, etc), and indicating issues when and where they are discovered.
Application Verifier also includes checks to predict how well an application may perform under various account privileges. These compatibility tests are used in Windows Logo program. you can free download Microsoft Application Verifier 4.0.665 now.
