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.

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."
