Windows 10 is out. We have begun to update our application pages to indicate apps that run under Windows 10. In the testing we have done on the preview version, we have not seen any application that refuses to run under Windows 10. I upgraded my home laptop to Windows 10 and I have yet to see a language application that won't run either. So if you see an application description that says it supports Windows 7 and 8, but 10 is not checked, my first guess would be that is a page we have not updated yet.
