How can I disable auto save content of disk to image on system shutdown? I have unchecked save to image in properties of disk, but it still save content to image at shutdown.
Is that on Windows 8 and up? You may want to disable hybrid boot as explained here.
This is because Windows 8+ features a so-called hybrid boot. Even when you shutdown the computer, it is not a real shutdown and Windows preserves the RAM disk's contents.
