WinNTSetup is a very classic Windows system image installation and deployment tool for Windows and Windows PE, developed by JFX from Germany. It enables user to install Windows OS directly in Windows or Windows PE, without the assistance of any CD/DVD, USB and other storage devices. For this reason, WinNTSetup is often considered as the best tool for implementing Windows installation from local hard disk - that is, a universal hard disk installer for Windows OS.

For privacy protection and data security purposes, it is very necessary to set a login password for the Windows user in use in many environments (especially the public places). But sometimes, we may forget our login password for those computers we don't use very often, or remember the wrong password, and fail to log in. This case, reinstalling the operating system is a inadvisable bad plan; and taking brute-force password cracking is extremely inefficient. Therefore, clearing the original user password has always been the first choice - also the easiest and most efficient way.

Ghost (short for General Hardware-Oriented System Transfer) is an excellent backup & restore tool (commonly known as cloning software) for system, data on hard disk/partition developed by the famous Symantec company from America. For the vast majority of advanced users like system administrator/network manager, it is used to backup the system partition (so as to minimize the time and labor spent on each reinstallation of OS furthest) or data on a disk.
