Hey All,

Thank you all so much for your help.

Many suggested the MS tools.  I tried those tools before turning to you
all for help.  The MS tools complained about trying to expand the active
file system.  It appears that the tools on Win7 Pro can not expand the
active system file system.  I tried both the GUI version where you right
click on the file system and choose expand, and the command line
diskpart command.

I used:

kpartx -av my.img to mount my image file

ntfsresize -P --force --force /dev/mapper/loop0p2 to resize the file
system to fit the previously expanded partition.

Widows ran a file system check, booted up, and now reports a 50GB
partition.  I'm happy, and Windows is happy.  Now I can proceed to
install a bunch of software on the newly expanded file system.
