Windows Explorer: right-click "open" option missing!

[kb3k]

When I right-click on a file in Windows Explorer, my "New, Open, Print, Save
As" options are gone! Does anyone know how to get these back? I can still
double-click on a file to open it, as well as right-click on it and choose
"open with...". I have no idea how this happened. I have not recently
installed any new programs or anything that I can think of that would have
changed the registry. Thanks!
