You could also use ntfsclone which is part of the ntfsprogs package to get
an image of the windows partition just after resizing the partitions.
ntfsclone -s -o sda1.img /dev/sda1
Now provided that the partition table entry does not change position or
size you can restore it to its original state with
ntfsclone -r -O /dev/sda1 sda1.img
The main benefit of this method is that ntfsclone understands empty space
in the partition and the resulting image is only marginally larger than the
actual data stored in the partition.
For example an ntfs partition with size 100GB having 20GB of data and the
rest being empty space could be backed up to a 20GB image file.
