Jose5, I can guarantee you that all versions of 7260 adapters support BT 2.1 , 2.1ERT, 3.0, 3+HS and 4 (BLE).
If the network is not showing the +HS could be because the driver installed was the OEM version for the BT (Bluetooth) portion.
This feature should be enable by default and if the name shows 4.0 then it is being recognized, but if you want to see the +HS, I would recommend to install first the wireless PROset 17 and then the new BT 17 version too.
Before the installation please remove all current network drivers and install the new ones again.
BTW option should be enable at BT settings as follows:
