What Changed

What Changed is a tiny Windows software solution that can monitor and log system changes, be they file modifications or new registry entries.

Although it could sound like rocket science to some less experienced users, it all comes down to just two different steps, both of them presented in the only window of the GUI.

First of all, What Changed needs to scan files and registry entries, so make sure you choose the targets.

The application creates a system snapshot and saves the current status of the system, while step number two is all about comparing the new data with the previously-collected one.

There are no secondary configuration options and that's a good thing for rookies, as figuring out the way the app works may be a little difficult in some cases. You're allowed however to copy file changes to a new folder and clean temporary files.

A good thing about What Changed is that it's fully portable and the whole package comes down to an executable file that can be easily copied on a removable drive. This means that no prior installation is needed, regardless of the Windows version running on your system.

On the bad side, What Changed doesn't track shift-deleted items and comparing the two snapshots sometimes takes a lot of time, but without any significant computer slowdown during the process.

Overall, What Changed is a very interesting piece of software, although a more user-friendly approach could make it even more appealing. It does what it says and comprises just the essential options to serve its purpose.
