Limitations and Considerations

• Dependency on Source Integrity: LastActivityView's output is entirely dependent on the presence and integrity of the underlying artifacts it queries. If Prefetch is disabled, registry keys have been cleared (e.g., using CCleaner or manually via reg.exe), or event logs are wiped, LastActivityView will not show the corresponding activity because the source data is missing. It doesn't perform magic; it aggregates existing data.

• Timestamp Source: Timestamps displayed are derived directly from the source artifact. A timestamp might represent the time of execution (from Prefetch), the time of file access (from OpenSave MRU), or the time an event was logged (from Event Logs). Understanding the source (often indicated in a dedicated column) is important for correct interpretation.

• Not Exhaustive: While it covers many common artifacts, it doesn't query every possible forensic artifact on the system. Advanced traces might still require manual checking of specific locations or the use of more specialized tools.

• Relationship to Manual Checks: For specific detections, like finding DLL paths in OpenSavePidlMRU, LastActivityView simply provides a convenient GUI overlay for data that could also be found manually browsing regedit. Its strength lies in aggregating this with other sources like Prefetch for a broader, quicker overview.
