How to backup Windows Registry using ERUNT

Windows registry contains settings, big amount of various information for the the Windows XP, Windows Vista, Windows 7 and others Microsoft Operating Systems. Before you make changes to the Windows registry or start a manual procedure of malware cleaning, I recommend that you make a backup copy of the Windows registry. You can save the backup copy to a location you specify, such as a folder on your hard disk or a removable storage device. If you make changes that you want to undo, you can restore the backup copy.

To backup the Windows registry I suggest you to use ERUNT. It is a free Windows registry backup and restore program. ERUNT can backup the Windows NT/2000/2003/XP/Vista/Win7 registry and important system files to a folder of your choice.
