Windows Update pushed out a new video driver for the Mobile Intel(R) 4 Series Express Chipset Family. One HP 6730b laptop was updated from 8.15.10.1872 to 8.15.10.2021. After the update the color depth is reported as 8-bit even if the setting is 32-bit. This means that Areo effects are disabled. Downgrading to 8.15.10.1872 did not help. Is there any way to force the video driver to report 32-bit color depth?
