DO NOT need 3rd party back-up. Win 7 comes with a good program to do the Back-up. Just go to control panel, select back-up and it will create an image file of your C drive plus the small 100 MB partition. When done it will prompt you to create a bootable restore DVD (you can use this disk, or any Windows 7 installation disk to restore the image file. Image can be on DVDs, or a 2nd HDD.
I have used it.
