The system language is changed or you receive a Stop error after you restart a computer that is running a preinstalled version of Windows 7: "0x00000021a"

Symptoms

Consider the following scenario:

  • You have a computer that has Windows 7 preinstalled.
  • You start the computer for the first time. Therefore, the Out of Box Experience (OOBE) wizard starts.
  • You set the display language to Chinese or to Portuguese.

    Note You notice that there are at least two entries for the language that you select.

In this scenario, you experience one or both of the following issues:
  • After you restart the computer, the system display language is changed to a random language.
  • When you try to restart the computer, the system cannot start and you receive a Stop error that resembles the following:
    STOP 0x0000021a
    Note This issue may occur up to several days after you start the computer for the first time.

Note These issues may also occur if you use Language Pack Installer (Lpksetup.exe) to manually remove a language pack on a computer that is running Windows 7 Ultimate, or Windows 7 Enterprise, or Windows Server 2008 R2.

Cause

These issues occur because the Lpksetup.exe incorrectly removes the language pack of the system display language.

After you run the OOBE wizard, Lpksetup.exe automatically removes the unused language packs. When it removes language packs, Lpksetup.exe compares language names instead of language codes. If a removed language and the current system language have the same language name, the current system language pack is also removed. For example, ZH-TW and ZH-HK share the name "Chinese."

Resolution

To resolve this problem, download the hotfix that is described in this article, and then apply the hotfix by using the instructions from your computer manufacturer. For information about how to contact your computer manufacturer, visit the following Microsoft Web site:

Note If the crash occurs because you manually remove a language pack by using Lpksetup.exe, you may have to repair the operating system before you can install the hotfix. To repair the system, use a system repair disc. For more information about system repair discs, visit the following Microsoft Web site:
