>>Not necessarily, sometimes the W7 does not have the drivers needed to recognize the device, in those cases you must refer to the vendor site for the device and there you can find the drivers or the news about on how to handle on each operating system.

>Thanks, do you mean contacting Dell for the Bluetooth support on the PC itself or the device I am trying to work with, such as keyboard and mouse?

Yes, I mean the Bluetooth vendor or any device that you are trying to connect to your PC. They must provide a driver for the respective operating system, but remember windows 7 is near to be ended in support and maybe they are not providing support anymore.
