Just found the solution from another forum
You may try it and tell me how it goes
Right click on "Computer" in the start menu and select "Properties"
Click on "Device Manager" in the left column.
Open "Bluetooth Radios"
Select "Generic Bluetooth Adapter". Open it and select the "Driver" tab.
Click "Update Driver"
Click "Browse my computer for driver software"
Click "Let me pick from a list of device drivers on my computer"
Click off "Show compatible hardware" --MS is stupid where this is concerned.
Select "Apple Inc." from the Manufacturer column.
For me, I know I have a Broadcom chip, so I selected "Apple Broadcom Built-in Bluetooth"
Click Next. Windows may try to dissuade you from installing the driver, but force it to anyway.
There saying that there is 2 blue tooth driver, one is generic by window 7 and the other is by apple.
