Using a PC, not a mac.

Downloaded Itunes. May have clicked on Live update. Whatever I did, my Itunes library was loaded with 60 tunes which I do not want. Tried to delete them, but Delete under Edit is grey.
Selected a tune to delete, hit delete on my keyboard and nothing happened.
Hit control+delete and nothing happened. Went to Edit, but Delete is grey.

Read somewhere that maybe I cannot delete if I have selected live update. Cannot find out how to opt out of live update.

What can I do to opt out of live update and delete unwanted tunes from playlist?
