I have an [HP Pavillion g6](http://en.wikipedia.org/wiki/HP_Pavilion_%28computer%29#Current_notebook_models) with Windows 7 and Ubuntu. On Windows 7, it says that my laptop doesn't have Bluetooth, so I thought that my PC doesn't support Bluetooth at all.

However, on Ubuntu, I have Bluetooth, and I can connect my phone to my laptop. I guess my Windows 7 is missing some drivers.

How do I fix it?
