Also, in Windows 10 the Windows Media Player no longer plays DVDs. This follows a trend at Microsoft of replacing their 'classic' desktop software with 'apps'. As the article linked below notes, Windows Media Player may be disappearing from the Windows ecosystem. Given that you are using Windows 10, when (not if) Microsoft decides to remove the Windows Media Player it'll be gone. You won't have a choice as it'll be removed during an automatic update.
Don't have any Apple products, but they do use a MacBook at the church. That thing gives me a fit. Some of it is because I am simply not all that familiar with it, but some of it is just Apple and the way they do things.
My preferred OS is Linux Mint. I use Windows 8.1 for audio recording and video work - primarily for church. I also maintain the church's tech crew laptop which runs Windows 10. Auto updates have bitten me more than once - including removing drivers for an audio interface that I needed to use the next day. Since then I have learned how to postpone updates, but you can never stop them as long as you continue to work online. Seeing as this computer is used for live streaming, well, staying off line just wasn't an option.
Hope that helps,
