I have a dell win 7 home premium disc just just came with my laptop. Can I use that disk to install Win 7 on a new desktop? Or do I have to buy another Win 7 full installation disk? Thanks
DVD's for same edition (except OEM) are all the same. You can use the same DVD to install on as many computers as you like. Each install must have a separate key, however. You may use the same key on a second computer if you remove it from the first.
