To investigate how a Windows application works, I need a software that will take a snapshot of the whole disk, including the registry and hidden/protected files, take a second snapshot after running the application, and show what changes were made.

I tried the free WhatChanged, but it takes a very long time to compute the changes.

Does someone know of a good application, either open-source or commercial?

Edit: I also tried InCtrl5, but it seems to miss some files.

Edit: For those looking for the same kind of application, RegShot can take snapshots of the Registry and the file system.

Is this continuing in your quest to circumvent the protection on the software on your other question for which a paid version has been suggested? –  Mokubai Jun 13 '11 at 12:14
Yes. I forgot to mention that I need a much older version, which is no longer for sale, hence the need to keep running the time-limited trial. I did offer to buy a license, but got no reply. –  OverTheRainbow Jun 14 '11 at 10:26
Many installer apps can detect all these changes. I know Wyse Installer used to do this. –  Keltari Feb 4 '14 at 19:16

Try Process Monitor.

Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity. It combines the features of two legacy Sysinternals utilities, Filemon and Regmon, and adds an extensive list of enhancements including rich and non-destructive filtering, comprehensive event properties such session IDs and user names, reliable process information, full thread stacks with integrated symbol support for each operation, simultaneous logging to a file, and much more. Its uniquely powerful features will make Process Monitor a core utility in your system troubleshooting and malware hunting toolkit.
