Currently I run Windows Insider builds on my second pc. The recent days it tries to update the build but everytime it reboots a GSOD will appear with a System Service Exception caused by "afd.sys". I tried the Windows update fixit tool and also did a sfc scan. Nothing helped. After the GSOD it needs manual reboot then recovers back automatically to 17677 and will download the next Insider build again.

  • What. Exactly is a GSOD? You tagged this question as BSOD? Have you used windbg to determine the cause of the BSOD?

  • @Ramhound actually a green screen of death. The one that appears on preview builds

  • @Ramhound in Insider Builds the BSOD screen is green. m0ddixx, have you tried downloading the last Insider via ISO and manually upgrade? Jun 14, 2018 at 14:07
  • You should still be able to use windbg to analyze the crash though. Wasn't aware they changed the color though.

    this was a bug, that Microsoft fixed in Build 17692 Jun 14, 2018 at 17:39

1 Answer 1


Microsoft fixed the issue in Windows 10 Insider Preview Build 17692

General changes, improvements, and fixes for PC

  • We fixed an issue resulting in some Insiders recently experiencing a bug check (green screen) with the error SYSTEM_SERVICE_EXCEPTION in afd.sys.

So check again for new updates and download the last Insider Preview.

  • The author might have to wait until a new Windows Insider Preview ISO is released. The only one that currently exists is for build 17127. Since build 17692 was released today it might be awhile.
