Hello, I have got the windows 10 upgrade icon on my £190 HP G72 Core i3 laptop I bought from ebay last week and have pre-ordered windows 10 to be downloaded on it once available on the 29th. However on my £850 gaming pc, I have not. I don't understand why, as I have installed all windows updates and my operating system is a windows 7 professional 64bit by dell. (Its by dell as it only cost £30 when I bought, I think it was the cheapest I could find at the time) There is no way that the pc hardware is not good enough as I have Intel I7 4790k processor, r9 280, ssd, 8gb ram etc. Does anyone know what could be going on? Thanks for any answers in advance.
