i tried to upgrade from windows vista to 7. it said that i have to deauthorize itunes. My question is this: although i have itunes, i dont have an itunes account so do i still have to deauthorize? and will i lose my songs if i don't?
If you have never authorized iTunes on your computer, you do not need to "deauthorize " it.
If you did and forget, you can authorize up to 5 computers. Then you can deauthorize them all and start again.
