Description

Each row is an executable path cached by Windows Application Compatibility, with file modification time, cache flags, index, and registry provenance. Use it to establish that Windows knew of a path and correlate it with stronger execution artifacts. AppCompatCache presence alone is not definitive execution evidence, and formats and flag meaning vary by Windows version.
