Microsoft has recognized a new bug in the Windows 10 October 2018 Update that significantly slows down the computer shutdown process. The problem apparently would occur due to a conflict with the USB Type-C controller.

In a recently published support document, Microsoft explains that on PCs with the 1803 version of Windows 10 installed, shutdown could take longer than usual when a device based on the USB-C standard is connected.

“An error in the implementation of the USB Type-C Connector System Software Interface (UCSI) in Windows 10 version 1809 may cause a delay of sixty seconds to suspend or shut down the system if it is started while the UCSI software is busy to manage a connection or disconnection on a USB-C port ” stated Philip Froese of Microsoft in a short post, which states that” the bug does not affect the normal operation of the USB-C ports and the machine. The system and ports should continue to function correctly when the PC is turned on or restarted”.

The bug affects all modern Windows 10 medium-high end devices that include USB-C ports. Also interesting to note that Microsoft in the same document did not disclose the availability of a fix to correct the problem.
