Windows 8 license backup

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 should pick up the Product Key and activate the system automatically.

If it does not, follow these steps:
