VHD (Virtual Hard Disc) is the copy set of the window setting, software, and all the modifications of the current windows installed on your PC.
This is like creating the same xerox copy of the pre-installed Windows and using that copy to be pasted on another computer. You get the same type of window settings and files by doing that.
