I have turned my SZ79 from Vista to XP and all the drivers and App. have been installed.
But I found out that, The S1 and S2 buttons are not functioning, and when I click to the sony control center, it said it can't be lanuch.
Do anyone know, What is the problem here, Thz

Most probably you have not installed sony utilities or vaio event service probably, try install them again, you should be able to use the S1 and S2 key.
