Hi I'm going to install windows 10 Home 64bit OEM onto my pc when I get it built. Im going to use a usb to install it and then buying a product key to activate windows. Will I get any problems doing it this way. I've hear of peoples Windows being deactivated after a few weeks even months. Im buying the product key from kinguin.net for £20 plus buyer protection in case the key is invalid/duplicated etc https://www.kinguin.net/category/22175/windows-10-home-oem-key/
