Is there a way to automatically commit EWF?

I'd like to find an easy way to always commit the EWF
overlay whenever I boot. Any ideas? There are no
situations where I'll need to manage the EWF overlay. I'm
using EWF to simply minimize writes to the flash disk.

I've tried a registry key at
HKLM\Software\Microsoft\Windows\CurrentVersion\Run to do
a "ewfmgr c: -commit", but it only runs when you log on.
Makes sense. A program needs a user context to run.

I could make a service that does a commit via the EWF
API. Or, make a change to one of my apps to do the same.
But, I'd like something that can be done from Target
Designer and not write or change apps.

Regards.

Well, you can commit at any time. I normally commit as
soon as I sign on. All my changes before and after the
commit are written when XPe restarts.

I just want to find a way to do this automatically at
boot. I already have a way to do it automatically when
anyone signs on.
