I apologize for another Returnil thread but I could not find the answers using search. 1. How does it affect the bootloader in Vista? I have 2 entries right now (for Vista and Norton Ghost rescue) in bcdedit. I don't want anything overwriting that and installing itself. 2. What happens to data that needs to be updated? e.g. Windows has to update the prefetch cache on each boot as it tries to optimize the load. Antivirus and various other apps update themselves. Apps need to update their AppData folders. From what I read I have to commit these changes every time before shutdown otherwise they will be lost (or in case of a crash). Is there a way to not virtualize certain folders? 3. Is there a way to install an app without first turning it off and rebooting. Like saying - persist all changes made by this installer. How does it handle apps that require a reboot to finish (as in most system utilities) Do I need the premium version or is the free one enough? Is there a performance difference between the two?
