Windows 10 Bug Makes the Shutdown Process Significantly Slower 

Shutting down a Windows 10 PC is slower if a USB Type-C device is removed during the process


A bug in Windows 10 causes the shutdown or system sleep process to be significantly slower than expected, with Microsoft explaining that it could sometime take up to 2 minutes to turn off your device.

And according to the software giant, it’s all because of a glitch in the way the USB Type-C controller is implemented in Windows 10, so the issue occurs only when USB Type-C device is plugged or unplugged when the system shuts down.

Of course, this affects pretty much any USB Type-C device, including here docks and chargers.No word on the fix just yetMicrosoft employee Philip Froese explains in an advisory that the USB Type-C device should still work properly when the system boots back to Windows 10, and no other issue occurs aside from the slow shutdown.

“A bug in the USB Type-C Connector System Software Interface (UCSI) software implementation in Windows 10, version 1809 can cause a 60 second delay in the system sleep or shutdown process if the power-down happens while the UCSI software is busy handling a new connect or disconnect event on a USB Type-C port,” Froese explains.

“Apart from the extra one minute the sleep or shutdown process takes in this circumstance, this bug does not affect normal functionality of USB Type-C on your machine. The system and the USB Type-C ports should continue to function properly after the next wake or restart of the system.”

Microsoft hasn’t said anything about a potential fix or an ETA as to when a full patch could land.

In the meantime, however, you can avoid the slow shutdown by removing the USB Type-C device from your system before sending the command to turn off the computer. Of course, you can also not remove the USB Type-C device at all, with the PC then supposed to shut down properly.

So problems in the 1903 version?


According to TechRadar...



Interestingly, Microsoft doesn’t mention any potential resolution for this bug, instead advising that the gremlin has been ironed out in the latest May 2019 Update, and that you should upgrade to this (Windows 10 version 1903).
