Ever wonder what changes an application is making to your Windows registry? RegFromApp is a simple utility that lets you pick a process and track any registry changes it initiates.

All you have to do is download and unzip the tiny application (just over 50KB unzipped), click the executable file and select a process to track. In other words, you don't need to install RegFromApp, and obviously it makes no chances to your registry.

You can also save any registry changes to a .Reg file which you can use to replicate (or possibly undo) the registry changes.
