Found that option eventually. Turn off fast start up was greyed out until I noticed towards the top of the menu an option "to change settings that are currently unavailable". I haven't tested the speeds yet.Ermmm. I recall seeing a video sometime ago that windows doesn't actually do a full shutdown if you have fast boot enabled.
It is something between suspend and shutdown.
Just googled to confirm and this may be interesting for you
