Sure, I can help with that. Using a product key on a new computer depends on whether the key is valid for the version you're trying to install. Windows XP keys are typically tied to specific editions, so check if your new system matches the edition the key was created for. If unsure, it's best to contact the manufacturer or retailer for confirmation.
