    yes and off the website and they don't work. i was looking around the windows folder and i found a text document called windows update and inside every line looked like this:
    2011-12-22 10:01:19:268 1180 3bc Agent WARNING: Failed to evaluate Installable rule, updateId = {D25C8B25-54F1-4834-B413-8A23D3A13E9D}.102, hr = 80070490

    I'm not sure if there are vista iso's available on the internet. you could google one. also don't think i can post a link here . maybe you could borrow one from your neighbor/friend?
