I've used System Restore before. It didn't seem to do the same thing. It really didn't. However, GoBack has a Microsoft credit in there right under Roxio inc. I think that the main differences to me are that GoBack has so many more restore points, it doesn't seem to take as much memory, and it does give you the option to keep any changes that you have made AFTER the restore point. Plus, it runs at system start up, and it only takes about 3 minutes to run with no reboot. You can even decide to "Go Back" at the last minute during start-up, and put your computer how it was before "That stint on the internet that really wasn't that great an idea"; saving any files you might ACTUALLY like.
