So...The only way to play your Music Library with 10, is with a 3rd party program? All my music is WMA......
It is a pretty safe bet that Windows Media Player will be in there in some form but it is unknown whether or not it will be able to play DVDs directly.
Rather than risking Microsoft eventually pulling the rug out from under your setup, a third party media player might meet your needs. VLC Media Player plays WMAs just fine (and the latest versions run under Windows 10). Foobar2000 is also a powerful music player with ripping, tagging and volume leveling features.
Unless you're still using Zunes, I'd suggest looking into FLAC (lossless) or Vorbis (lossy) as there aren't any nagging questions about their future and they're probably a little more broadly supported.
