Don’t want the “Open With” Option..?

Each application's subkey in HKEY_CLASSES_ROOT\Applications controls whether that
particular application will show up on the dialog box. If you want to ban a particular program
from the Open With dialog box, look for the application's subkey underneath
HKEY_CLASSES_ROOT\Applications, add a String value named NoOpenWith, and leave
the value blank. There will be no more “Open With” menu for that item.
enjoy!!!!!!
