How to get my videos from my iPhone onto my computer?

Firstly i have windows so i can't do the easy mac way with the program thing.
secondly i have searched all over the internet and nothing has helped at all…
i don't get a auto use screen pop up, much like a memory stick
the device doesn't show in the mobile device under computer
the photos and videos are no where to be found in the itunes media file after syncing, yes the box is ticked in itunes for videos.
i could email them but i don't want to lose quality and they are rather big, and youtube is just no as well.
Nothing is working at all!

It is pretty easy. Only you just have to connect your iphone in to your PC via the cable… Then windows will automatically install necessary drivers. And then Auto Play window will appear on the screen, select "open folder to view files" option from the window. Then you can simply copy paste anything like usually doing.
