ERUNT - The Emergency Recovery Utility NT

ERUNT is a freeware  written by Lars Hederer for Registry backup and restore for Windows NT/2000/2003/XP.

Windows 9x/Me had option to automatically create backups of the registry at startup, with Windows 95 always backing up the registry from the previous Windows session, and Windows 98/Me maintaining up to five registry copies from the last five days where Windows was running. Unfortunately, Windows NT and 2000 do not automatically backup the registry, and in Windows XP, full backup of registry cannot be taken without using System Restore program, which cannot even be used for a "restore" in case a corrupted registry prevent Windows from booting. Further, Registry hives cannot be copied to another location because they are all in use by the Windows.

ERUNT provides the easy solution. It offers:

• Backup of Windows NT/2000/2003/XP registry to a folder of your choice.
• System and current user registries selectable.
• Command line switches for automated registry backup and restoration.
• Restoration of registry in Windows 9x/Me/NT/2000/2003/XP and MS-DOS (all-in-one restore program) or the Windows Recovery Console.

Using ERUNT command line switches, you can perform an automated registry backup, without user interaction. The syntax for the ERUNT command line is as follows:

ERUNT DestinationFolder [sysreg] [curuser] [otherusers] [/noconfirmdelete] [/noprogresswindow]

Description of the command line switches is as follows:

DestinationFolder
	The name of the folder where the registry backup should be saved. All parameters except DestinationFolder are optional. If you specify a destination folder on the command line, ERUNT automatically runs in "silent" mode and with default backup options(system and current user registry).
sysreg
	Backup the system registry.
curuser
	Backup the current user registry.
otherusers
	Backup other open user registries.
/noconfirmdelete
	Automatically deletes the contents of the destination folder if it exists, without asking the user.
/noprogresswindow
	Hides the progress window during backup.
