While yes, you do need to increase the NTFS file system, I'd expect what
you'll find is the partition still needs to be enlarged first.

In the past I've booted up with a GNU/Linux live CD that has GParted and
enlarged the partition that Windows occupies. Expect Windows to do a check
disk (I think) following the resize.
Or [instead of using GParted] I'd expect you could boot to a live
environment and use fdisk to delete the Windows partition (after marking
down the start of the existing partition). Then create an NTFS partition in
the same place that is of the larger desired size. From there you might be
able to boot your Windows OS and have it resize ... but I don't know for
certain (though worth a test if you have a backup and don't mind testing
it!).
If you were feeling adventurous, you could also loopback mount it and
choose my second suggestion with fdisk. But if you had gparted or ntfs-3g
you could also use utilities to manipulate the disk and file system.
Certainly not as easy as booting a live CD in the VM (let alone GParted
GUI).

Please back up your VM's disk image/backing before trying any of this. ;-)
