If you use your Lenovo Recovery disk, there is no need for a Product key.

Hello Zaref,

I'm not sure what you are trying to do, but you will not be able to use your Windows 8 product key in Add Features.

hello
i'm afraid of losing my serial number because my laptop gone mad those days
it often works well but sometimes it becomes very slow especially when i open photoshop PSD files
i'm afraid that i'd have to reinstall windows and i don't have the serial number
i'm sorry for asking too much

Have you made the Lenovo OEM manufacturer's Recovery Disks?

No worries. Ask all that you need to ask.

It just gets confusing if you don't reference what you were wanting to do. That's all.

On OEM PC's that come with Windows 8 pre installed, the Product Code is embedded in the BIOS. Official Windows 8 install media will read and use it automatically. My Windows 8 TechNet ISO's read my laptops embedded code and install the matching Core edition automatically without prompting me to enter a code. It then activates online automatically. If you don't have any install media I would recommend creating your recovery media while you still can.

ok
many thank ^_^
