ThinkPad Bluetooth 4.0 on Windows 10 version 1607

Windows 10 Anniversary Update

It cause a lot of trouble. A lot of apps hangs on copy&paste operation or just hangs without reason.

After update Win 10 to 1607, bluetooth on Thinkpad T430 stopped working. It shows connected devices but it does not work.
