Do not blame Valve faggotry on Windows Vista.
Far from it, Valve didn’t like the ATI drivers on my laptop and I had to wait 6 months before they fixed CSS so I could play it again. Now Valve doesn’t like Nvidia’s OpenGL drivers, apparently Nvidia’s release of OpenGL is unsupported by CS1.6. Leave it to Valve to screw up drivers that haven’t been touched in a decade or so.
