how to enable bluetooth icon in task bar in rmbp with windows 8

• The bluetooth icon dose not be showed in task bar in rmbp with windows 8.
• The device of bluetooth dose not work correctly in device manager of windows 8 with the yellow exclamation mark.
• The windows system event log shows BTHUSB alerts and error with code of 3 and 17. The driver is unloaded.
• Some apple magic mouse's functions can work, without sliding to navigate.
• The current OS is in bios enumeration mode with MBR and The logged user is in the normal account and the bootcamp is newest.

I have remembered that the bluetooth was good without above problems when the windows 8 was installed firstly and the bootcamp can not work in administrator account. After being restored NVRAM with option+command+p+r and reinstalled windows 8 enterprise 64 completely again, it shows these problems when the bootcamp works well.

Except the first windows installation, the second time is selecting EFI boot and the last time is in normal mode, which has no difference in the bluetooth problem. In a normal or administrator account, the same problems appear.
