It is a major update at around GB for the Pro edition, so Windows 8 devices will take a while to install Windows The amount of time it takes to download will vary depending on connection speed and how busy Microsoft servers are. Some antivirus software might interfere with the installation. After you install Windows or Windows RT , remember to turn your antivirus program back on. Get the free update.
