hdiutil mount example.dmg

The best option, whenever possible, is using 7-Zip. You probably already have it if you're a Windows regular, since it's a free and convenient way of extracting the more universal ZIP format.

Once Z-7ip is installed, find the DMG file you want to work with in File Explorer and right-click on it. In this case we're using some of Apple's free system fonts as an example.Mouse over '7-Zip' in the right-click menu, then select 'Extract Here' or 'Extract files.' That should give a choice of where to send extracted material, though by default the app will create a subfolder in your current File Explorer location. Click 'OK' once you've chosen a place.
There's a good chance you'll have to dive into the new subfolder and run extraction again. With Apple's font DMGs for example, the real meat is buried within an HFS archive, which you'll need 7-Zip for. HFS is a filesystem used exclusively by Macs.
That should be it — you may see a lot of confusing folders and files, but what you want should be buried in there somewhere.
