The registry editor is a rather sensitive part of the Windows operating system, and you should always be careful when using it, as a single wrong change can crash the system. Unwanted registry changes can even affect your user experience. Sometimes you even need to monitor and compare changes made to the registry by a program.

We have already seen how to monitor registry changes with Process Monitor, RegShot, WhatChanged or the integrated fc.exe tool. Now let’s see how to use RegFromApp to track, capture and compare registry key changes made by a program.

Nirsoft RegFromApp is free portable software available for Windows x64 and x86 machines. Once you have downloaded it, open RegFromApp.

Here you will find almost all the programs you have installed on your computer. Select one and press button OK .

Then the selected program is saved with each change:

RegFromApp has no complicated settings. However, you can change the display mode . There are two different display modes: Display last modified values and Display original values.

One thing you should note is that you need to download the 32-bit version of RegFromApp if you want to monitor register changes of a 32-bit program. For example, if you are using the 64-bit version of Windows but have installed a 32-bit version of Google Chrome. Then you cannot use the 64-bit tool to monitor your 32-bit chrome.
