WhatChanged is a lightweight system tool designed to quickly detect changes in your Windows registry. It operates in two simple steps: first, it captures an image of your current registry status, and then it compares this image to a new one taken after changes are made. For optimal results, the initial image should be taken immediately after installing WhatChanged. This tool is ideal for monitoring registry changes before and after installing new software. Simply perform the first step before installation, and you're all set. WhatChanged offers a fast and efficient way to keep track of your system's registry modifications.



Decent app overall. It has its moments, like how it organizes tasks, but occasionally the performance dips. I like it for now, but there are a few things I’d change if I could. Let’s see how it evolves!
