This article describes an issue when you try to run the WinPE setup for Windows Server 2012 R2. This issue is resolved in hotfix 2932246 that has additional steps of configuration.


Consider the following scenario:
  • You have a computer that is running Windows 8.1 or Windows Server 2012 R2.
  • You try to create a multilanguage image for Windows Server 2012 R2 that includes the Thai server language pack.
  • You copy the WinPE boot.wim file from the Microsoft Assessment and Deployment Kit (ADK), and you insert the necessary optional components from the WinPE_OCs folder including:
    • th-th\
    • th-th\
    • th-th\

    By default, these files are located in the following path:
    C:\Program Files\Windows Kits\8.1\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs
  • You run the setup for this image.
In this scenario, the WinPE setup user interface (UI) that should be localized in Thai is not displayed correctly. Instead of Thai characters, some square boxes are displayed.


This issue occurs because the required Thai font is not included with WinPE, and because some required optional components are also not included in the ADK.


To resolve this issue, follow these steps:
  1. Download the hotfix that is described in this article. The hotfix includes the Thai font in the file.
  2. You copy the file to the WinPE_OCs folder that is located in the ADK installation.
  3. You insert the WinPE_FontSupport_WinRE optional component into the boot.wim file being used for Windows Server 2012 R2 that includes the Thai language pack.
  4. You can then run the setup for this image.
