We have already seen how to monitor registry changes using Process Monitor, RegShot, WhatChanged or the built-in fc.exe tool. Now let us see how to use RegFromApp to track, capture & compare registry key changes made by a program.

Compare Registry changes made by a program

RegFromApp from Nirsoft is a free portable software available for Windows  x64 as well as x86 machines. Once you have downloaded it, open RegFromApp. Here, you can find almost all the programs that you have installed on your computer. Select one and hit the OK button.

Following that, whenever that selected program makes any change, it will be stored like this:

RegFromApp has no complicated settings. But, you can change the Display Mode. There are two different display modes, i.e., Show Last Modified Values and Show Original Values. One thing you should keep in mind is that, if you want to monitor registry changes of a 32-bit program, you will have to download the 32-bit version of RegFromApp. For example, if you are using a 64-bit version of Windows, but you have a 32-bit version of Google Chrome installed. Then you will not be able to use the 64-bit tool to monitor your 32-bit Chrome.
