Applies to: Windows Server 2012 R2 DatacenterWindows Server 2012 R2 StandardWindows Server 2012 R2 Essentials

This article describes an issue that occurs on a Windows 8.1-based device in the out-of-box experience (OOBE). A hotfix is available to fix this issue. The hotfix has a prerequisite.


Consider the following scenario:
  • You have a Windows 8.1-based device connected to a network. 
  • Access to the network is controlled by a SIM card.
  • The SIM card has a PIN associated with it. The PIN must be entered before network access is allowed.
  • You start the device for the first time.
In this scenario, when you're prompted to enter the PIN, an error occurs during OOBE and OOBE crashes. 


To fix this issue, we have released a hotfix. Even though this issue is observed only in Windows 8.1, the hotfix also applies to Windows RT 8.1 and Windows Server 2012 R2.

Note This hotfix has to be installed by the OEM. You can’t install this hotfix on your own because it has to be in place before OOBE starts.

Important If you install a language pack after you install this hotfix, you must reinstall this hotfix. Therefore, we recommend that you install any language packs that you need before you install this hotfix. For more information, see Add language packs to Windows.
