If you want to to let Windows Media Player automatically find album info online, you can manually do so at this point by right clicking on the CD icon and bringing up a submenu that includes "Find Album Info" as an option. If you see your album, highlight it and hit "Next." This will bring up a verification screen and you can click "Finish." Besides updating your Rip info, this will also update your Windows Media Player library with the new album and track details.
If you don't have an Internet connection or if Windows Media Player can't find your album, you can update the album and music info manually in Windows Media Player by right clicking on each individual piece of info you want to edit (e.g. Unknown Album, Unknown Artist, Track 1, etc.).
Before you start ripping, note the check marks next to each song. This indicates which songs will be ripped. Feel free to uncheck any songs you don't particularly care for and don't want ripped. Once you're all set, you can then click on the "Start Rip" button.
