DiffMyRegistry is a utility application for Windows designed to monitor and analyze changes to the Windows Registry. It helps users identify exactly what has been altered in the registry following the installation of a program, the application of system tweaks, changes to settings, or the execution of specific software.

Key Features
Flexible Snapshot Creation
Registry Compare can capture registry snapshots with three different scopes:
- Entire registry: captures the state of all root keys.
- Specific root keys: such as only HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE.
- Specific subkeys: targets only relevant branches—for example, HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion—resulting in a faster process and more focused results.
Comparing Two Snapshots
Compare two snapshots (taken before and after an event) to view changes in detail:
- Added: new keys or values that have been introduced.
- Deleted: keys or values that have been removed.
- Modified: values where the data has changed, including a comparison between the old and new values.
Snapshot Explorer
Browse the contents of a snapshot much like you would in the Windows Registry Editor, without affecting the system’s actual registry. Users can navigate the key structure, view values along with their types and data, and examine the state of the registry as it existed when the snapshot was taken.
Exporting Comparison Results
Comparison results can be exported into three formats:
- HTML: a clean, easy-to-read visual report, ideal for documentation or sharing.
- TXT: a simple, lightweight, and universally compatible text report.
- CSV: structured data that can be opened in Excel or used for further processing.
Use Cases
- Analyzing registry changes made by installers or uninstallers.
- Locating specific registry entries associated with Windows settings for the purpose of system tweaking.
- Detecting suspicious or unwanted changes to the system.
- Documenting configuration changes for system administrators.
