What's the best option for getting video files from my iMovie to my friends windows laptop?

I have video/audio files that can only be found in my iMovie on my MacBook Pro. My friend who has a windows laptop needs them, how do I get them to him? What's the best option for this considering the different formats possible.

I've attached a screen shot of my Mac's details.

Thank you very much for reading my q & I look for to hearing your a.
