The Bluetooth item in Control Panel on a Windows Vista SP2-based computer does not work as expected
when you click the item

If you need drivers try your System Maker's support site and/or the actual device maker's site.
BluetoothView is a small utility that runs in the background, and monitor the activity of Bluetooth
devices around you. For each detected Bluetooth device, it displays the following information:
Device Name, Bluetooth Address, Major Device Type, Minor Device Type, First Detection Time,
Last Detection Time, and more. BluetoothView can also notify you when a new Bluetooth device
is detected, by displaying a balloon in your taskbar or by playing a small beep sound. http://www.nirsoft.net/utils/bluetooth_viewer.html
Hope this helps.

Hi There,
Actually your solution to your problem is simple, I was in the same situation few months ago, and i have managed to resolve th problem,
Please follow the steps below

Download the 'Windows Mobile Device Center' ( current version is 6.1 ) which you can download it from http://www.microsoft.com/windowsmobile/en-us/downloads/microsoft/device-center-download.mspx
this works for both Vista and Windows 7. I've tried it on both.
- Install the downloaded software but it may not look like it worked on Windows 7 PCs. Vista automatically configured the settings on the bluetooth devices but for those who have Windows 7, here are the things you should do:
- Go to 'Device Manager' from 'Control Panel' -Or- just right-click on Computer Icon and choose 'Properties' and then click on 'Device Manager'.
- You'll see an 'Unknown Device' named 'Bluetooth Peripheral Device'
- Right-Click it and click on 'Update Driver Software' -Or- anyway you find it easy to bring up the Update driver window.
- Click 'Browse My Computerfor Driver Software' button.
- Click 'Let Me Pick from a List of Device Drivers on my computer'.
- Select 'Bluetooth Radio' from the list if it asked you to select and then in the next window, it will show a list of drivers with Company Names in one list and Drivers in another. In the Company List choose 'Microsoft Corporation', not only Microsoft.
- From the drivers list there may be one or more drivers with the name 'Windows Mobile-Based Device Support' with different driver versions. Select one or the latest.
- Ignore any warnings and keep pressing next and then Finish at last. If all goes well, the last screen will show the message that device driver is successfully installed.
Now, after manually updating the driver for your bluetooth device, in 'Device Manager' when you click on 'Bluetooth Radios', it should display one more item which will say 'Windows Mobile-based device support'.
There are few more things that you want to pay attention to. If you have already added the device in your 'bluetooth device list' that didn't work, then remove the device and add it again. After you add it, you might need to restart the computer if it gave you a connection problem error message.
Every PCs that had Windows 7 and Vista worked after installing this software and I hope it will work for you too.
Regards
