Although I now use Windows 10, I'm not familiar with the way it rips CDs. However, I'd be surprised if it doesn't do what many rippers do - they go online to find CD track listings and album art.
Trouble is, they use databases that have, over time, been populated by other rippers. They've often filled in track details with spelling mistakes and mixed up labelling / poor / incorrect album art.
My strong advice would be to ensure all details / album art is exactly how you want it early on. In other words, don't get 100+ discs in before you decide how you want the metadata to look. There are programmes that can make bulk changes to metadata, but it's better to know how you want it before you get into it. (I won't pretend this is fun - people have given up after starting to rip CD collections. Personally, I couldn't charge someone enough money to rip a large collection properly for them!)
Album art by the way, is stored, usually as a jpeg, in the same folder as the FLAC files. Devices that display album art see the jpeg as you play the files in the folder.
The easy bit is the FLACcing, it's the metadata tagging / album art that's the real faff (if you want to do it properly) and that's why backup is absolutely essential.
See what Windows 10 finds when you load a CD ready for 'Rip to FLAC'.
Stand by to learn a hell of a lot as you go along!
