This problem often occurs after a program or software installation adds something to the Windows "Context" menu (the menu you see when you right click on an item). The problem could be as simple as uninstalling the last program installed or you may have spyware or a virus.
On Windows, when you right click on any item, Windows searches the registry for a list of appropriate items called Shell Extensions. Basically, these are dll files and applications chosen to perform a task for a given item when a user right clicks on it. Depending upon the situation in which you right click, you get a specific list of possible actions you can take - like Send To, Copy, Paste, Rename, ect.
To begin troubleshooting this problem, I need to know what programs you might have installed prior to the problem. Also, have you noticed anything strange about Windows Explorer on your computer - such as taking longer to open files, the "Start" menu button looking hazy when you click it, start menu taking longer to pop up?
I'll help you as much as I can...
