I am planing on doing a reinstall of my OS and had specific questions about Returnil 1. What is the main difference between Returnil and a Virtual "OS" or is it pretty much one and the same? 2. I am currently running a trial of it now to see if I want to add it on with the fresh install but wondered about software updates, MS updates, desired downloads and installing programs. Do I always have to reboot to make it "stick? 3. Because of it's "dream" environment, does Returnil help protect the registry?
