Hi there
My name is Jon and I am an independent technical adviser. I would like to assist you with your question.
You can convert wma files from a CD to mp3 files using Windows Media Player built in to Windows 10.
First of all, you need to get WMA file from CD to your computer. Insert CD and open it with Windows Media Player, click on Tools > Options and select Rip Music tab. Then specify the location you want ot rip music to and choose MP3 as the Format. After that hit OK to proceed.
You can also use VLC Player which is a free 3rd party application.
