My Vaio laptop is 18 months old and the other day the hard drive fried and I lost everything, including the recovery partition to reinstall. I've installed a new hard drive now, and reinstalled Windows 7 from scratch. First thing I did after it was set up was visit the page for my model (SVE1711R1EB) and download all of the drivers listed, expecting that this would set most things back to how they were.

However, one thing that I used to use a lot was an icon in the system tray which linked to a widget to enable/disable wifi and bluetooth; it used to open automatically on start-up too. Having installed all the drivers I'm disappointed to note that it's not there, and I can't find where to get it from.

It was a little icon with a green square containing an upward and a downward arrow. How do I get this back?

I should add that wi-fi works fine but I don't always want it running - this utility was a fantastic way of easily switching wifi on/off.
