매우 매우 간단하죠?

FindWindow로 TASKBAR의 클래스 이름을 얻어옵니다.
ShowWindows로 표시를 해줄지 말지 결정합니다.
UpdateWindows로 윈도우를 업데이트 해줍니다.

결과가 나옵니다.

so, so simple !!

P.S 1. CodeProject 에 가시면, 더욱 더 많은 기능이 있습니다 ~_~..

제가 허접이라서 Ctrl+Alt+Del 은 왜 그렇게 했는가 잘 이해가 안가네요. ( 라는 것도 있지만서도 귀찮아서.. 소스도 길고.. )

P.S 2. 주석까지도 그대로 베껴왔습니다. ㅇ_ㅇ...;
