Start the registry editor by clicking Start, then, Run, and then entering regedit.
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Desktop\NameSpace.
Each sub-key here represents items on the desktop. Look at each item until you find one with a (Default) value of My Bluetooth Places.
Delete the key that contains the My Bluetooth Places text. Delete only the key containing the My Bluetooth Places item—don’t delete the entire NameSpace key.
Refresh your screen and the icon will be gone.
