Had a good question this morning:
I seem to have lost the toolbar for Internet Explorer. I can't copy, paste, etc. like I used to. Would you be able to tell me how to restore it?
I believe you are referring to the Menu Bar. To make it appear just tap the Alt key on the keyboard and it will appear.
To put it back for all time, move the mouse up to the top of the browser window and right-click. Then click the line that says Menu bar. A check mark should appear indicating you have added it.
