AppCompatProcessor is a digital forensics tool designed to extract and analyze data from Windows AppCompat and AmCache artifacts at enterprise scale. The tool processes registry data to provide insights beyond traditional stacking and grepping methods commonly used in forensic investigations. It works with AppCompat data structures that Windows maintains to track application compatibility information and execution artifacts. The tool requires Python 2.7+ and libregf library with Python bindings for registry file processing. Installation involves setting up libregf dependencies either from source distribution packages or directly from the GitHub repository, followed by installing Python requirements through pip. AppCompatProcessor supports both OSX and Linux platforms, with Windows platform support temporarily unavailable but expected to return. The tool is particularly useful for forensic analysts working with large-scale Windows environments where AppCompat data analysis is required for incident response or threat hunting activities.
