This is not the first post with this issue.
I previously had Windows 7 and the Windows 8 Preview edition. Once I upgraded to Windows 8 Professional, my bluetooth adapter no longer is available in the device manager and Bluetooth no longer appears in the Control Panel. I have tried every suggestion and downloaded the new versions of the Widcomm software, the drivers that have been suggested, checked my bios and can't seem to find a place to get the bluetooth adapter to be seen.
