위 코드 실행시 Program Files 밑에 barosearch 폴더가 없는데도 :barosearch 코드가 실행되는 이유가 뭘까요??

IF EXIST %ProgramFiles%\barosearch(

여기다 reg delete 코드넣어도 폴더가 없는데 레지를 삭제합니다...

)

그리고 reg delete "HKLM\SOFTWARE\Microsoft\Internet Explorer\Extensions\{57D1CDEE-1880-484f-8361-55D7626D2679}" /f

extensions 이게 뭐하는건가요?? 일단 {57D1CDEE-1880-484f-8361-55D7626D2679} 이 값만 삭제하도록 했는데..

다른PC에서 이 값이 같은지 다른지 알수가 없네요... 같다면 문제 없지만.. 다르다면.. extenstions를 통쨰로 날리고싶은데..흠흠..
