Arduino Leonardo Problem with windows 10 when OS reboot

Arduino Leonardo OS: Windows 10 IDE: 1.6.5

I have install arduino driver correctly and it's work fine under Win10

It's show Arduino Leonardo(COM1) in device manager's COM port category.

After the OS restart, the OS can’t recognized this arduino device It's in device manager's other devices category and can't communicate with it.

I re-install driver, but it's still not working. I must click the Reset button on the board or unplug and plug the USB connector every time i reboot OS on my pc.

I think this is not smart and cause everyone's trouble.

By the way, It's all work fine on Win7 & Win 8.

Anyone or Official arduino who can help to save this driver's problem on windows 10 ?
