The AppVerifier focuses on two specific categories of tests: tests
difficult to perform due to vendor system limitations and subtle
problems difficult to diagnose on Windows XP Professional. Its purpose
is to help vendors write stable applications on Windows XP Professional
and future versions of the Windows operating system. The latest version
of the AppVerifier is included in the Application Compatibility Toolkit.
The Application Compatibility Toolkit for Windows XP contains documents
and tools to help Windows customers diagnose and resolve application
compatibility issues. For the most recent release of the toolkit,
