Windows Update KB3105208 Causes Blue Screen For Some Windows 10 Users (Updated)


Update: Microsoft has pulled the latest update and users won’t be able to download it anymore:

Microsoft recently released KB3105208 update to Windows 10 Insider users. This update is causing blue screen for some users. Microsoft is aware of the situation and they have removed the update for now. Gabriel Aul from Windows team provided the following info for Windows Insiders who are experiencing this issue.

Sorry everyone for the impact this update had on you. The Windows Servicing team has been working since late last night to understand what is happening here, and is pulling this package down as soon as they can.

As many have mentioned, the temporary workaround is to disable Secure Boot so that your machine can boot correctly. Once we have a fix for the issue we definitely want you to be sure to re-enable Secure Boot for your protection. I’ll share more info on that when we have a fix in hand.

The series of hotfixes that we’ve been sending out are actually mostly “empty” (they include some config changes and test binaries) and have been for the purpose of testing our delivery pipeline. So this definitely caught us a bit by surprise that it was having this impact. We’re debugging what the precise cause was, but this happening to you likely exposed a bug that we need to address – so I hope you at least feel good as an Insider that you prevented this from happening to less technically savvy customers.

Thanks everyone, and sorry again that today was a tough day to be an Insider.



In the short term, this appears to be the easiest path to resolution:

  • Boot UEFI, disable Secure Boot
  • Enter Bit-locker key if required
  • Boot into OS
  • Uninstall KB3105208
  • Reboot machine to ensure full uninstall
  • Re-enable Secure Boot

If you’ve already tried a system restore, the path to resolution looks to have a few more steps and I’m working to outline that right now.

Once you’re back up and running, please do re-enable Secure Boot.  KB3105208 has been pulled from the WU server, so when your machine scans for updates again, this update will not be re-offered to your machine.
