Reading that now, I see I didn't make a whole lot of sense, sorry about 

On Windows 7 x64 (I haven't tested XP), upsdrvctl shutdown doesn't 
appear to get called during automatic OS shutdown by NUT. I used upsmon 
-c fsd to test. upsdrvctrl shutdown works if I run it manually.

I could probably configure an instant command to send shutdown.reboot 
just before shutting down the OS. My test UPS only provides 1min 
(non-adjustable) which isn't always enough time for Windows (XP 
especially), so this hack is not ideal.

This is directed to anyone on the list who might know. I'm deciding if I 
want to switch to low battery shutdown as NUT seems to prefer that 
method. I've typically just used a 2min timer for desktops. Also, with 
the way NUT works on Windows right now, the UPS will drain itself even 
more because it doesn't shut off.
