Macrium Reflect Free is very good too. It allows you to create an image of the Windows (and any other) partition online using VSS technology, it makes compressed and verifiable (with embedded hashes, no comparison to the imaged partitions) images and you can easily make with it a Linux/Windows PE rescue CD/USB stick to use in order to restore the Windows partition, if you have to, from the created images. The only problem is that in order to use the Linux rescue CD the image must be on another hard disk drive (whereas with the Windows PE rescue media it can be on another partition of the same HDD). You can also mount the created images and restore individual files/folders from them. I use it for some time and I am very satisfied.
