Sisin,
может так?

Код:

@echo off
set "sPath=%SystemRoot%\System32\regsvr32.exe"
::if not "%Processor_Architecture%"=="x86" set "sPath=%systemRoot%\SysWoW64\regsvr32.exe"
set "xDLL=C:\Windows\system32\ntshrui.dll"
call :prov "%xDll%"
pause& exit

:prov
 reg query "HKEY_CLASSES_ROOT\CLSID" /s /f "InprocServer32" /k /ve|>nul find /i "%~nx1" && (
  echo Зарегистрирована [%sPath% /u "%xDll%"]
 ) || (
  echo Не зарегистрирована [%sPath% "%xDll%"]
 )
exit /b
