Windows VISTA Aero needs 32 bit
I don’t know if you did know that Windows VISTA with Aero needs 32 bit to be set so you can enjoy Aero interface.
Can happen when you update your video card driver, if you before had 16 bit, after that to still have 16 bit, and because of this, the AERO interface to not work even if your Windows is Genuine.
To make it work, right click on your desktop (work space), choose Personalize, after that click on display settings, and under colors choose Highest (32bit).
Warning! Older PC’s, do not support 32 bit, read your monitor and video card manuals before you set it to 32 bit to avoid any possible damage that might happen if does not support it.
