VLC Media Player has the capability to create FLAC files from an audio CD.  It has "lua" scripting.  So, place the script below into the directory:

VideoLAN\VLC\lua\extensions

Then, in the View menu, you'll see a new option called "Audio CD to flac".  Enter the number of Tracks in the track field, then press Apply profile, and then press Enqueue converting tracks.

Now, the CD to flac conversion will be in your play list - so click View -> Playlist, and then press the big play button.  The CD will be converted to flac files, and placed in your C:\temp directory.

Here is the listing of the lua script (you could call it cd_flac.lua - is is based off of the post at   https://forum.videolan.org/viewtopic.php?f=29&t=130354    ):

profiles={
{"Audio CD -> flac", " :cdda-track=? :sout=#transcode{vcodec=none,acodec=flac,ab=128,channels=2,samplerate=44100}:file{mux=flac,dst=\"C:\\temp\\Track ?.flac\"}"},
}
