Item being sold is a micro sd card which is 256GB in size preloaded with the Windows 11 Home version of the OS. It does not come with an activation key whatsoever. All you will need to do is plug it in to your steam deck and then boot to the drive. All of the drivers are loaded up and ready to go. There are no games loaded onto the card, just the Windows install.

Let me know if you have any further questions
