RegShot is a handy little tool that enables you to view the exact changes made in the Windows registry entries, by comparing the “before” and “after” registry log files.

The user interface of RegShot is pretty standard, and there are no special or hidden features that can be found here.

You can select the type of format of the compare log file (text or HTML document), set the output destination path, and optionally scan a particular directory or add a comment into the log file.

How does it work? You take the first shot, the second one, and then compare results. For example, if you want to know what changes are made in your Windows registry entries when you install a software, then use RegShot to take the first shot before installing the respective software, and the second shot after the installation process is complete.

Why is this helpful? For instance, if your system starts to act strange, then you know the exact source of the problem, and fix it with a registry cleaning tool. Otherwise, you can learn the inner workings of your computer system.

When a shot is being taken by RegShot, you can view the number of keys and values it has detected, as well as elapsed time. The shots can also be saved, in case you want to compare two registry log files that were not consecutively taken.

RegShot works perfectly in most cases, but it needs several seconds to take a shot or to load the log file. Plus, it uses a massive amount of memory for such a small application.

All in all, RegShot is definitely welcomed on any computer system, so we strongly recommend you use it. It is free, after all.
