They currently have a web player beta going, https://beta.music.apple.com/ https://beta.music.apple.com/, but personally I use https://vusic.site/ https://vusic.site/ because the apple beta is a little unstable and it suits my needs. iTunes for windows does support Apple Music, but iTunes is still a pig and best not installed on your PC.
