  1. Hi, thank you for the great guideline. I am following it to upgrade to Windows 7.
    Hope you can help the the issue I am facing with the Intel Chipset Device Software.
    The link takes me to Intel® Chipset Device Software (INF Update Utility) version 10.0.13 (Latest).
    However, when I download and check the Release Note, seems that this update is not for chipset of Latitude D520. Could you help me because I am not sure about that.
    And in that case, which version of chipset device software should I update for my D520?

    Thank you very much!

    1. I always install the latest version, it will update the chipset. I am on a D820 which is the same model with a bigger screen and used many of the same drivers.
      Heres a screenshot from the Intel Update Utility:
