What the hell is spigiot ? <| sep |> The feeling is mutual . <| sep |> The ocellated turkey is on the front page of Bing today . Not sure if this is a synchronicity or not . <| sep |> I ' m too attractive <| sep |> If you look on the bottom of the laptop , you ' ll see a sticker with a product key on it for a certain version of Windows . If the person who sold it to you installed Windows 8 on it when the sticker actually says Windows 7 , then you can only install 7 for that machine . If they actually bought a legit retail copy of 8 and stuck the new Windows 8 sticker on it , then you can use that . Just download a clean iso , use Rufus to install the iso to a USB , then install with that key . If you don ' t have a sticker or matching key , then you could theoretically use Speccy or some other software to extract the key for your current installation and write it down to use during reinstallation . That ' s the legit way to do it without paying for a brand new license , as far as I know .
