IE7기본 설정저장이 안될떄(Internet explorer 7 unable to save settings)

처음 설치시(또는 IE8설치후 다시 IE7사용시..)
설정저장을 해도 Internet explorer 7 unable to save settings라는 메세지가 계속 뜨고
홈페이지로 자동으로 접속이 안될때..
상황은 일단 IE8(정식버젼)을 지우고 다시 IE7로 돌아왔을때 였다.

This problem may happen if you register shdocvw.dll after installing Internet Explorer 7. This is just another side-effect caused by the registration of shdocvw.dll in a system running Internet Explorer 7. For more information, see Why doesn't the "You've opened a new tab" message go away?

To fix the problem, follow these steps:

1. Click Start, Run and type Regedit.exe

2. Navigate to the following location:

HKEY_CLASSES_ROOT \ TypeLib \ {EAB22AC0-30C1-11CF-A7EB-0000C05BAE0B} \ 1.1 \ 0 \ win32

3. Double-click (default) and set C:\WINDOWS\system32\ieframe.dll as its data.

4. Exit the Registry Edit
