Bash script can help you. Example
(for it to run on Windows you need the following cygwin packages: cygwin,  
coreutils, wget
and either associate .sh extension with bash, or create a shortcut to bash  
with a parameter):

===========================
fn=<YOUR_FILE_NAME>
url=<URL_OF_YOUR_FILE>
if [ \
"`date -u -r <YOUR_FILE> +'  Last-Modified: %a, %d %b %Y %X GMT'`" \
!= \
"`wget -S --spider $url 2>&1 | grep Last`" \
]; then
mv $fn `date +'%m%d%y'`-$fn
wget $url
; fi
===========================

Assuming the file already exists in current directory.
This script compares last modification time of <YOUR_FILE> and  
<URL_TO_YOUR_FILE>.
If they're not equal, existing file is renamed and a new file is  
downloaded.
