Scanreg is a Windows utility that creates a backup of your computer's Registry file, a file that contains information about the programs and documents on your computer. Scanreg and its Restore option is not part of the Windows 7 operating system. The utility is part of Windows 95, 98 and ME operating systems. To backup your Windows 7 Registry file, you must use the utility Backup and Restore.
Accessing Backup and Restore
To backup your Windows 7 Registry file, click "Start" then enter "Backup" in the "Search programs and files" box. The Windows search utility will run automatically. Click "Backup and Restore" under the "Programs" heading. The "Backup and Restore" dialog box will open. Click the "Create a system image" link under the "Control Panel Home" heading. Click the circle next to the drive you want to save the backup file to, an external drive or DVD, then click "Next." Click the check boxes next to "(C:) (System)" and "System" then click "Next." Click "Start backup" to begin the process.
Like Scanreg, Windows 7's Backup and Restore creates a copy of your computer's system files and Registry configuration information. The utility also backs up the System.dat, User.dat, System.ini and Win.ini files as well as user account information and preferences. If backing up your system to DVD discs, make sure you have enough discs to complete the process. The Backup and Restore utility will inform you of the backup's total gigabyte size. A single-sided DVD disc holds approximately 4GB of data.
Restoring a System Image

Click the "Restore my files" button once the "Backup and Restore" dialog box opens. Click "Restore all users' files" then follow the on-screen prompts to select the drive or first DVD disc containing the backup file.
