概要：
Since Longhorn was tweaked and optimized before turning into Vista, this software does not transform the host PC into Vista per-se, but into a variant of it that was the initial take Microsoft took on the OS.
Before applying the transformation though, it is highly recommended to backup the original files, just to be on the safe side of things and make sure restoration is possible in case anything goes wrong.
