Application to take snapshot of files/registry?

Question

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.
