Deactivate hibernation, Windows 7 - How to?

I have Windows 7 on Dual boot with Ubuntu 12.04.I have set swap file size
to 0 on Windows, therefore hibernation is not possible, at least not to be
done right.Sleep is done normally and resuming is instant, too.However, my
computer is, by default, set to go on hibernation after 1-2 hours of
sleeping.So, whenever I boot Windows after many hours of sleeping, having
apparently been on hibernation, it acts as if it had an unexpected
shutdown and gives me options for normal boot or to go on safe mode.Of
course, the system is not resumed where I left it, but starts from
scratch.If I let it happen many times, it perfroms a disk checking on
startup.
So my question is, how can I disable the hibernation feature? Although I
set swap file to 0,I saw no setting explicitly giving me the choice to
enable or disable the default hibernation setting, so is rational to
assume that is is still enabled despite the non-existent swap file, and
that causes the problem.
