Its too big. The one I'm downloading is a smaller package meant for home users. The 250 MB version is meant for mainframes and multi-user computer workstations.
I went to the Windows Update page, and it told me to install it, with these details:
Total updates selected: 1 items, 75 MB, 3 hours 56 minutes
yeah right. four hours. even if I wanted to, my ISP probably would disconnect before it was finished (peoplepc).
