InstallSpy 2.0

InstallSpy by MJLSoftware is a lightweight, precision tool that shows exactly what an installer changes on your system. Designed for IT administrators, developers, and security-conscious users, it captures file, registry, service, process, and configuration activity in real time and presents it in clear, searchable reports. Create before-and-after snapshots to see precise diffs, track dependencies, and identify leftover artifacts. Use these insights to troubleshoot failed installs, craft clean uninstalls, and keep environments documented and compliant.

Key features:

• Real-time monitoring of file, registry, process, service, and optional network activity during installs
• Before-and-after snapshots with human-readable diffs and powerful filters
• Smart grouping of changes by installer, component, and location for faster triage
• Exportable reports (e.g., JSON, CSV, PDF) for audits, tickets, and change records
• Rollback guidance and cleanup checklists to remove leftovers safely
• Silent and unattended install detection, plus command-line support for automation
• Custom alerts to flag risky behaviors or unexpected changes
• Privacy-first design: analysis runs locally; you control what leaves your machine

InstallSpy helps teams reduce troubleshooting time, minimize configuration drift, and keep systems clean and predictable. For edition details, system requirements, and licensing, visit MJLSoftware.
