    will appear as “Tech-Preview” in dropdown.

    For a quicker download just rename your “LIVE” folder to “TECH-PREVIEW”

    Looks like they found a crash last second so they’re holding off for a bit to investigate.

    UPDATE: looks like they’re cancelling for tonight and going to try to fix it in the morning.
