Customized means the driver is somewhat changed by notebook manufacturer (Toshiba, Dell, HP or such...) - that's why i asked for manufacturer and model number

.. with that information i might be able to find out what they customized in their driver (prolly they fit in only a brand logo...)
the graphic driver 7.14.10.1227 ( = 15.2.1.1227 )you have is installed is very old ( March 2007) - but what Intel calls their "latest" driver for Vista 32 bit is from March 2009 (

) ... :
15.12.4.1666 ( = 7.15.10.1666)
