Iâ€™ve always wanted a piece of software like this. I could have used it when working on a VBrick codec problem a few months ago.
You could think of it as VMWareâ€™s â€˜snapshotâ€™ technology, without using VMWare.
For instance, say you want to test out a new version of Adobe Acrobat. You install it while this software is running, and it takes note of all the system changes. Later on, you decide that you donâ€™t like the new version of Acrobat, so you want to remove it without relying on the uninstall program to do the right thing. Bang, just reverse the â€˜layerâ€™.
It is free for personal use so Iâ€™m definitely going to give it a whirl.
