I have installed windows 7 ultimate 32 bit on my vaio. And the windows was ok but the most of the options of the notebook doesn't worked, for example some of the function keys like those who change the brightnest of the screen, the volume, AV mode key, S1 key, some of the functions of the mouse pad. Now i am with the original windows vista ( a used the recovery discs to format and restore my default windows and settings ) but i still whant to be with the windows 7 .
Ou and i almost forgot! Whyle i was with the windows 7 i tried to install some of the utilities and drivers from here : http://support.vaio.sony.eu/computing/vaio/downloads/updates/index.aspx?l=en_GB&m=VGN-FW21E&os=10 but some of them didn't wanted to install, or didn't install properly.
