CRegistry Comparison is an open-source utility that works by creating a snapshot list of all registry files on your computer. Once that list is made, you can run a comparison against it at any time to see changes. This tool is especially helpful for tracking registry files changed when installing and uninstalling programs.
To start, you’ll need to install CRegistry and make a New CRegistry snapshot.
After clicking the New button, CRegistry will prompt you to select a folder to save your CRegistry files into. Note that these aren’t registry backups, just snapshots of what your Registry looks like on this particular day..
Once you have a CRegistry file saved you can install a new program. Once your new program is installed run CRegistry again browse to your old CRegistry file, then click compare. Here CRegistry will list every single change to the Windows Registry that happened since you created the previous file.
If you want to archive what change occurred, you can use the File Menu to Save Results from the comparison.
Overall CRegistry is a groovy little tool that lets you track Registry changes otherwise difficult to follow. For the cost of free, you can’t complain about its lack of features or visual graphics. It works fantastic for what it is supposed to do.
