RegShot

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

Advantages to a portable app and easy-to-use environment

The installation process can be skipped altogether as this product is portable. This means that it is not going to affect the Windows registry and you can take it anywhere with you, by simply moving it to a USB thumb drive or other similar removable device.
The user interface of RegShot is pretty standard, and there are no special or hidden features that can be found here. It encompasses a few buttons and some boxes and thus, both power and novice users can easily find their way around it.

The actual process and choose log extension

You can select the type of format of the compare log file (TXT or HTML document), set the output destination path, and optionally scan a particular directory or add a comment into the log file.
You are required to take the first and second snapshot, and then just compare the results. For instance, if you want to know what changes are made in your Windows registry entries when you install new software, then use RegShot to take the first shot before installing the respective software, and the second one after you complete the installation process.

Information available after taking a snapshot

This type of utility becomes quite useful, when your system starts to act strange, as it helps you identify the source of the problems with ease, so that you can 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.

Performance and conclusion

RegShot works perfectly in most cases, yet it needs several seconds to take a shot or to load the log file. In addition to that, 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 suitable for both power and novice users and our tests did not reveal any errors or crashes.
