App "G" preventing shutdown or restart

After updating my Windows 10 to creators update (build 15063.138) when I restart or shutdown the PC a screen appears and shows a 'G' app which is preventing the operation.

Is there a way to determine which application it is, or find out more details about it?

I do not see any "g" running process or installed application in my system.

Solution 1:

Process Monitor will give you much more information about what is running and what those processes are doing.

https://docs.microsoft.com/en-us/sysinternals/downloads/procmon

  1. Begin the shutdown
  2. Cancel once hung
  3. Run Process Monitor and see what is going on.

Then enable verbose shutdown messages:

  1. Run gpedit.msc from the Start menu search
  2. Go to Computer Configuration > Administrative Templates > System
  3. In the right pane, double-click on Verbose vs normal status messages

You can also get detailed information about shutdown using the Windows SDK:
