My friend has a lap top originally Asus with Windows 8. We started a project to update it to 8.1 and ready for Win 10. He has 3G mobile net, which is sometimes very slow. With update something get wrong cause the result seems 8.1 but is not perfect. Metro does not work and Windows update shows it is not functioning. I am afraid the Windows 10 can not reach ever his lap top cause Win update does not work. Asus Importer does not take any worry of this problem. Is Windows 10 available in DVD's? How we could get it due to poor Internet? What the disks costs?
