For cleaner removal, use an iOpener or hair dryer to heat the sticker.

Use a pair of blunt tweezers to peel back the large sticker on the back panel to reveal the second screw.

You only need to peel this sticker to where you can access the hidden screw. You don't need to pull it completely off.

Technically, these are tamper-evident stickers, but don't worry—Microsoft can't legally void your warranty, as long as you don't damage anything. Have fun!
