[Session hung at logoff on Windows Server 2012 R2]

Hi every one. We have the same issue with XenDesktop 7.7 and VDA version 7.7. After update VDA to 7,8 the issue doesn't fix. 

 

Also we disable USB device rediretion and Usb plug and play device redirection, but it also doesn't help us. Maybe someone have any positive update?
