    Hi there,

    Customer changed environmental variables value by clicking on my computer, properties, advanced, environmental variables, edit (user variables), and changed Variable value to the word "windows".
    Now windows gives us a blue screen and does not load from any other mode, not even from safe mode.
    I tried to boot from CD in order to perform a recovery but it gives me a blue screen (pci.sys error).
    I can read the hard drive on another PC, no problems.
    I was wondering how to change the environmental variables back to what it was.

    Thanks in advance
