Documentation & Full Scope
Windows utility capturing registry states before/after software installations, uncovering stealthy modifications, MITRE ATT&CK persistence triage, and 1-click Undo Rollback (.reg) generation.
Key features
• Baseline, change something, compare. Every added, changed and removed key and value in one list.
• Autorun changes flagged with MITRE ATT&CK. Run keys, services and shell hooks are classified so persistence stands out.
• CSV, HTML, JSON and .reg rollback. Hand the result to a SIEM or undo the change with a generated .reg file.
• Scan presets and built-in noise filters. Quick triage by default; filter Windows telemetry churn so installer changes stand out.
What you get
• One self-contained Windows download (.exe), nothing to install: the .NET runtime is built in.
• Editions: Free (evaluation), Personal (2 PCs), Professional (5 PCs) and Team (25 PCs). One download serves every edition and your licence key sets how many PCs it activates.
• One-time purchase, the key does not expire.
Requirements: Windows 10 (21H2+) or Windows 11 (64-bit).
Updates for 12 months, errata always free. Support: contact@mdanamulhasan.com
