    My wife's HP laptop had Vista running with Avast antivirus. Recently,
    internet connection has stopped responding. Googling reveals this is a
    result of an Avast bug. She uninstalled Avast, problem won't go away. Tried
    all the fixes. Seems to have corrupted something in Vista. I don't see any
    way to "repair" Vista. How can I do a repair installation (like I do for
    Office corruptions or on XP)? One thing we want to avoid is having to do a
    clean install/deleting all existing programs/docs.

    PS: She can't find the Vista disc that came with the laptop (maybe -- so
    many of these things no longer come with discs), but does have a valid Key on
    the laptop.

    If you press F8 button as it boots, then select Advanced options and you
    can repair from there.
