Windows 10’s latest update is causing a string of issues for users and it looks like Microsoft has also shipped a buggy update to old Surface PCs. Windows Update KB4516067, which was shipped to Windows 8.1 RT devices like Surface 2 and Surface RT, comes with a critical bug that breaks Internet Explorer completely for almost everyone.

KB4516067 is a monthly rollout update for Windows 8.1 and Windows Server 2012 R2. It includes protection against a new subclass of speculative execution side-channel vulnerabilities and security updates to core components.

After applying KB4516067, users are reporting (1, 2) that devices like Microsoft Surface 2 and Surface RT fail to load Internet Explorer with the following error:

  • Error: The certificate has been revoked by its certification authority. See DefaultBrowser_NopublisherId in event viewer.

Microsoft online support chat team appears to be aware of these reports. Someone from the team told me that Microsoft is “already aware of the system update issue causing the application not to run”.

“Microsoft is currently working to fix the problem,” the representative said.

It’s worth noting that the issues highlighted here appear to be widespread. If you experience any of them, you can remove the botched update from Surface 2 or any affected device to run Internet Explorer.

How to fix Internet Explorer on Surface

To uninstall the update and resolve Internet Explorer’s certificate error, follow these steps:

  • Open Start.
  • Select Control Panel and navigate to Programs > View installed updates.
  • In the search box in the upper-right corner, enter KB4516067.
  • Select “Update for Microsoft Windows (kb4516067)” and click on Uninstall.

You will also need to disable automatic Windows Updates to avoid installation of the same patch again. To turn off automatic updates, simply open Services and disable Windows Update service.

You can also open the Settings and reset the device to resolve the problems.
