I have two Machines (laptops) Both running Windows 7 Ultimate 32bit First Machine, One I can go to Control Panel > Display > Adjust Brightness First machine, has been running Windows 7 for few months. Second Machine, If I do the same steps, I can not find Adjust Brightness. Second machine, has been running windows 7 for only one one week. Is it waiting for a an update that will include that feature? Both machines, I have loaded Windows 7 Ultimate from the same DVD Attached a screen shot.
