Trying to autostart xbmc + send to tray (xp)

Hi, I've been trying to autostart xbmc and minimize it to tray on startup..
The second part is easy, i used trayconizer.

But auto-starting xbmc has been a problem for me.
My xbmc setup is a little different,

My drive C is deepfreezed (for public usage)
and i need to update the userdata quite often,
so i have to create userdata folder in drive D (which is not deepfreezed),
then use junction function from Link shell extension
to replace userdata in C,
so that the userdata can still be updated even though C is deepfreezed.
I also use firedaemon to force xbmc to act as service..

But strange thing is, when i test it on startup,
xbmc starts with confluence or the default skin (I use a customized skin),
which means that it can't find the junction-ed userdata folder from D.
So that means junction isn't working...

But when i test it manually by opening xbmc, it works, it found the junctioned userdata folder..

Does this mean junction function starts after shell service (daemon)?
Anyone know another way to accomplish this?
