Sony Vaio - Windows 8 Drivers help!!

Hi,I did a clean install of Windows 8 on my Sony Vaio SVS15115FNB. I know I should've gone for an update, but read somewhere clean install is always better. Coming to the point, all my Fn keys (except volume) seems not to work. Neither I am able to turn off the track pad or use Sony utilities. I called my Sony Customer Support to ask about supporting drivers for Windows 8 - all they say is, I should install windows 7 again and try upgrading to windows 8 (not a clean install). But the thing is I failed to take backup of windows 7 - and I am almost stuck up.My requirement is simple, I somehow need to install the Vaio Control Center (I need to use that Battery Care option), turn off track pad, make Fn keys work - can someone guide me?It seems I will have to wait for Sony to release the updates (which I don't know when). I don't see Vaio Control Center under Windows 7 drivers list too - Is there any solution? How should I solve these issues?Thanks!

Windows 7 drivers are binary compatible with Windows 8. You can use them without problems in 95% of the cases.
