  1. So to bypass the waiting game for the new windows 10 upgrade, I went to the microsoft website and downloaded the available ISO. I am positive I have the correct version but when I put in my product key, it says product key does not work. I tried running lazesoft key finder and used the "product key" it found, which strangely was different from the one printed on the sticker on my PC, but it didn't work either.

    I'm running:
    Windows 7 home premium x64

    I downloaded:
    Windows 10 home x64 ISO

    Any ideas why it gave me that error?

    Ive tried this disc on 3 PCs now and none worked

    Right. During the install it isn't that clear, in fact, during the 10 install I entered my 7 Pro key because I was installing 10 Pro and it didn't work. Left it blank and continued. Once I got into 10 all was good and it was activated.

    Two days ago I tired of waiting too but didn't download the ISO. You can jump the queue by downloading Microsoft's Media Creation Tool. This will set in motion the download and automatic validation.

    Windows 10 is now installed on my atom netbook as an upgrade from Windows 8.1. The start of the process identified me by name and after a couple of hours everything was completed. I kept all my documents and programs. Apart from a complaint from Samsung's Magician software about the screen resolution not being supported everything seems to be OK.

    I suggest that you do not download the Windows 10 ISO directly unless you are happy to tackle validation issues.
