NirSoft RegistryChangesView

Free Download NirSoft RegistryChangesView for Windows PC. This is a lightweight utility for comparing Windows Registry snapshots to efficiently track changes.

Overview of NirSoft RegistryChangesView

This handy program allows users to take a snapshot of the Windows Registry at a specific point in time and compare it with another snapshot or the current state. It’s ideal for identifying modifications made by software installations, configuration tweaks, or malicious programs. Created by NirSoft, it delivers this advanced functionality in a simple interface without requiring installation.

How It Works

The software captures the full structure of your system’s Registry and stores it in a snapshot file. Later, you can load another snapshot or even your current Registry and compare the two. The tool will then show added, removed, or modified keys and values. It’s incredibly useful when troubleshooting, testing, or debugging.

Snapshot Comparison Options

What sets this tool apart is its flexibility. You can compare:

• A previous snapshot of the current Registry.
• Two previously saved snapshot files.
• A snapshot with a shadow copy file (Volume Shadow Copy).

This opens up options for tracking background changes made without user awareness.

Clean Interface With Detailed Results

Even though it’s a technical tool, the interface is user-friendly. Once a comparison is done, the results are displayed in a clear table format. You’ll see the path, action (created, modified, deleted), old and new values, data type, and even timestamp details. You can also export the results in HTML, CSV, or plain text formats.

Portable and Lightweight

It doesn’t require installation, meaning it’s completely portable. You can run it from a USB stick or external drive. It utilizes minimal system resources and starts quickly, making it ideal for IT professionals, support teams, and power users who require Registry insights without added overhead.

Ideal for Software Testing

If you're trying out new software and want to know what changes it makes under the hood, this tool is perfect. Take a snapshot before installing, then one after. The difference between the two tells you exactly what the program did to your system’s Registry.

Use With Shadow Copies

One advanced feature allows you to retrieve Registry data from shadow copies. This means you can investigate changes that happened in the past, even if the system state has changed since then. It’s a powerful feature for forensic analysis or deep system inspection.

Simple Yet Powerful

What’s remarkable is that, despite its small size, the software packs a powerful punch. You get accurate results, flexible comparison modes, export options, and a clutter-free experience—all without digging through complex menus.

Exporting Results

Once you've identified the differences, you can save or export them. Whether you're generating documentation, sharing with team members, or keeping a personal log, the export function supports common formats like HTML and CSV, making the reports easy to read and share.

System Requirements

• Operating System: Windows 11/10/8.1/8/7
• Processor: Minimum 1 GHz Processor (2.4 GHz recommended)
• RAM: 2GB (4GB or more recommended)
