Guys all OEM laptop keys are the same. Friend's key is the same as your key as long as the Windows edition installed is the same. OEM SLP keys are like that.

-- the key on the sticker is only needed if something happens to the Bios from the manufacturer where the factory installed license will not activate. The manufacturer uses the same key for all of their MOBOs during the factory install but are required to include the unique code on the COA certificate to show that they have purchased a copy of the license for every system they ship. Sometimes these preinstalled keys will stop working if you update the BIOS for some reason (ie. to update the list of supported CPUs, etc.) on the system and then you need the code on the sticker in order to get the activation working. So while the key may work for activating another system it is not a legal use of the code and could result in problems down the road if\when you need it for a reactivation of the laptop license and doing so would be a violation of the EULA and considered an illegal copy of the OS.
