Windows has a trick for that. It actually hibernates the OS, GUI, Drivers etc when you shut down, just without any apps running. This way it can come back up in seconds.

You'll notice that after you install a new device driver it'll boot much slower. This is because it invalidates the hibernate image and does an actual boot next time.

It's also why it won't let you fiddle with the BIOS settings before it does a quick boot. Because the hibernate image presumes the exact same hardware configuration.

And it doesn't unmount partitions when you shut down so if you use Windows one day and Linux the next you have to boot up Windows first and then reboot into Linux so that Windows will unmount its partitions, otherwise Linux can't mount them.

Oh yeah good point. I forgot about that.

Linux updates also wreck bitlocker if the windows partition is on the same drive (which I have to use for work) so I left the whole dualboot thing behind.
