SYMPTOMS

Consider the following scenario:
  • You install the Traditional Chinese language pack on a computer that is running Windows 7.
  • You install some services that execute Windows Management Instrumentation (WMI) queries during the startup process.
  • You restart the computer.
In this scenario, you experience a delay of approximately two minutes during the startup process.

Note You may experience this issue if the following two registry entries exist and contain the text "Binary mof failed":

Location
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WBEM\WDM
Entries
  • C:\Windows\system32\drivers\zh-TW\ACPI.sys.mui[ACPIMOFResource]
  • C:\Windows\system32\drivers\zh-TW\battc.sys.mui[BATTCWMI]

CAUSE

This issue occurs because some localized files are mismatched when WMI tries to compile the Managed Object Format (MOF) classes for these files in the WMI repository. Therefore, when there are multiple WMI queries, the WMI service stops responding.

Windows 7 file information notes
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    VersionProductMilestoneService branch
    6.1.760 1.17xxxWindows 7SP1GDR
    6.1.760 1.21xxxWindows 7SP1LDR

WORKAROUND

To work around this issue, delete the following two files, and then restart the computer:
  • C:\Windows\System32\drivers\zh-TW\acpi.sys.mui
  • C:\Windows\System32\drivers\zh-TW\battc.sys.mui
Important After you delete these two files, you may experience this issue one more time when you next start the computer. However, the issue is resolved after one successful restart.

After you delete these files, certain Advance Configuration and Power Interface (ACPI)-related event log entries and performance counters may be displayed in English instead of Traditional Chinese. However, these event log entries and performance counters are rarely used in ordinary situations.
