So I guess i'll move the question to a new thread.
When transferring data from a previous machine to a new machine, you open the old drive on the new machine and attempt to navigate to the previous user account in the documents and settings folder or users folder and the new Vista, 7 or 8 machine says that before you can access this folder it the OS must take ownership.
But if you boot into a bartpe environment and try to load that exact same folder, it will open up first try and the files are visible and copyable clear as day without taking any sort of ownership.
This happened with me when I recently set up a new build--set up the OS on a SSD and used the old drive with all my files on it as a secondary/storage drive. I'm just going through doing that as needed, but it's quite normal, since the files were created/owned by a different SID on a different system.
Because BartPE doesn't have to take ownership we know it's not a security measure of the file system on the previous drive. So we know it is possible to read files without taking ownership, is it the case that Vista, 7 and 8 cares to much? Or does it have something to do with UAC?
