I doubt windows 10 is why the simulator isn't working. It's probably a browser compatibility issue, especially if you're using Chrome or the old simulator (the plugin web unity player probably has installed correctly for some reason) Try switching to a different uptodate browser, until you find one that works. Or you can press the skip simulator button located at the bottom of the badge instructions.
Another option is: you can use the new simulator which should be appearing on all badges soon, as the default simulator. To do that, go to the main badge index and select 'new simulator: skills and drills'
