Dell wireless 365,370,380 Bluetooth module is the most common Bluetooth device that Dell uses. Its normally supports Widdcom Bluetooth driver  which is manufactured by Broadcom and Modified by Dell ......But dell has removed Windows 8 support In some old Windows 7 laptops like N5010.....

But fortunately the windows 7 drivers are working fine on windows8 and most of them are installed during the windows installation....But the main problem is the Bluetooth driver (Dell Wireless 3XX module)   

Broadcom has released their Bluetooth driver for Windows 8 PRO.....the Broadcom Bluetooth 4.0 driver has  support for a lot of Bluetooth devices and Dell Wireless  3XX Bluetooth module is in the support list.....But as Broadcom don't provide drivers directly to customers.... they give it to the system manufacturers like Dell, Lenovo, HP, etc. and the modify it for ease of their customers.

So here is the Broadcom Bluetooth 4.0 driver from Lenovo site which is running fine on Dell 365 Bluetooth  device without any compatibility issue and also you can use Bluetooth Control Panel as you do in Windows 7
