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.

    Manually configure your system to start in a minimal boot configuration with AutoRuns and manually determine which entry is starting the application in question – Ramhound Apr 15 '17 at 20:42
  • Unless you think it may be an important process, there should be the option to force the shutdown. A process with just "g"as the name strikes me as a little sketchy though. I'd run a scan if I were you. – Carcigenicate Apr 15 '17 at 21:35
  • I think the problem is the utorrent. When I disabled the utorrent from the startup the problem disapered. The pc will shut down or reboot but I have to wait for it to close the program. It's annoyinga. – Wetropos Apr 17 '17 at 19:47

    Are you using Geforce Experience? Because I am getting this too, and I am not using Utorrent, I don't know what is it.. – Anonymous May 26 '17 at 21:33
  • I am experiencing this and am using both uTorrent and Geforce Experience. So my bet is that it is the Geforce Experience app, especially given that the app is called "G" – Evan Teran Jun 04 '17 at 03:34
  • I am not using geforce experience. For me the problem is utorrent – Wetropos Jun 17 '17 at 04:56
  • Can you force the shutdown via cmd/powershell? (shutdown.exe -s -f -t 00) – Bennett Yeo Nov 19 '17 at 23:29

    I've been having the problem for several months, both on 17.05 and 17.11. Using Process Explorer I fail to see any processes named "G" ca. fifteen minutes after a reboot. (I will check again tomorrow, and edit this comment if I find it then.)

    When G is the only process stopping reboot and I tell Windows to quit anyway, it quite without apparent problems.

    To the best of my knowledge I'm not running utorrent or Geforce.

    I have seen this message too several times over the past few months. I do not have a GeForce chipset, nor Google Chrome, nor any Torrent software installed. The machine is very clean with no indication of malware. I could not find any G.exe on the drive. – Michael Dec 11 '17 at 00:45

    it looks like Google Chrome backup feature, per reddit .. https://www.reddit.com/r/techsupport/comments/70xke5/app_called_g_is_preventing_shutdown_or_restart/ – c69 Dec 29 '17 at 12:36

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:

Yes has a way to find the hide process and kill it. But for that you will need a special tool called "Process Explorer" you can download it from here.

I never hear a process called "G" , but sound like it's a rundll32.exe task , so find it on the process explorer and have a look in the tree of process running under the rundll32.

PS: If you don't find the process in the Process Explorer the chances of you have a malware/virus/worm is big. So my suggestion is to have your PC scanned with a good anti-virus.

See here for Microsoft's explanation:

"We investigated and found an issue where windows related to GDI+ were only referenced as 'G'. We've fixed this, so going forward, these will now have the name 'GDI+ Window ()', where will show the .exe name of the app using GDI+," the Windows Insider team said.
