If you have a valid Windows 8 product key (no matter whether OEM or retail, whether upgrade or the full product), you can produce an iso file using the Windows 8 Setup Tool. Download and execute the file Windows8-Setup.exe from Microsoft, enter your product key, and have the tool download the Windows 8 setup files.

With Windows 8/8.1 The Product Key on preinstalled Operating Systems (HP, Acer, etc) is embedded in the BIOS in the Motherboard, so that the lost and/or worn C.O.A. Sticker problem is no more.

When you reinstall it will pick up the Product Key and activate the system automatically.
