I have scripted TBLocked.bat to determine if the Internet Explorer 7 Toolbars are locked.

The syntax for using TBLocked.bat is:

\[call\] TBLocked Status

                              Where Status is a call directed environment variable that will contain:                                              L - If the Toolbars are locked.                                              U - If the Toolbars are unlocked.                                              X - If the status is unknown, an error condition.
TBLocked.bat contains:
                              @echo off                              if \{%1\}==\{\} @echo Syntax: TBLocked Status&goto :EOF                              setlocal                              set key="HKCU\Software\Microsoft\Internet Explorer\Toolbar"                              set Status=X                              for /f "Tokens=3" %%a in ('reg query %key% /V Locked^|find "REG_DWORD"') do (                               if "%%a" EQU "0x0" set Status=U                               if "%%a" EQU "0x1" set Status=L                              )                              endlocal&set %1=%Status%
