There are several ways to do what you want for free (record the LPs that is, not get a Bentley)
But to do it for free is not going to be a simple load one program, click here type operation, it would involve at least two separate programs, one to record the LP and another to burn it back to CD
audacity will let you record from the line inputs on your soundcard and save the result as a MP3 for free.

And windows media player will let you burn the MP3s back to a CD (you already have media player)
These are only suggestions of two programs that will do what you want, there are many others. but if you want a simple load one program click go type answer then you will probably have to pay for it.
