Just thought I would post that I went ahead and upgraded my OS to Windows 7. I just finished about an hour ago and the problem with Shogun2 crashing at exit seems to have gone away. In addition--an issue that I had with Empire not starting after my previous GPU upgrade has also been fixed.
I had put off going Win 7 until now, and just like i mentioned, I was really prompted to do so because of a TW game. I think this officially makes me Creative Assembly's b*tch now.
Cheers
