Hello guys and ladies 
Recently i reintalled windows 7 on my Vaio pc. When i tried to install the drivers i had some problems some of them are missing or they are not installed correctly ? For example FN Keys, i couldnt find the drivers, also the driver for the " Base System Device "... I downloaded the drivers from the sony website for windows 7. Any ideas how i can solve that kind of problems ?

Hello again
The link for the " Base System Device" helped alot.
However, i didnt manage to fix the Fn Keys... i follow the instruction in video but nothing.
After the video from youtube i tried others solutions from the internet and still it doesnt work. Like to check in services , to install the drivers with another order or other drivers with a spesific order.
I found two sony firmware extension parser device driver. the first had exe file but the second it didnt had... How i install the second one ?
Also, i noticed that some key sequence like alt+shift ( keyboard language) , or alt+shift+esc ( task manager ) , or the TAB key doesnt do anything when i type or when i use the browser... I connect the keyboard from my dekstop pc and all worked fine. I checked the settings and are all ok .Driver or Hardware problem ?
Should i return to Vista OS or it can worked with Windows 7.
Thanks for your tine and sorry for my english
