Many people are killed in the Deathly Hallows but after? That's the last book. Harry Potter and the Deathly Hallows. Unless your talking about the epilogue but that's still part of the book.
In the Deathly Hallows
It is not sure that winky died or not as there was no mention of her in the deathly hallows ,so we can assume that she survived in the battle of Hogwarts.
