“New Word Document” missing from right-click context menu?
I have Office 2007. When I right click the folder screen of the "Windows Explorer" in order to create a new Microsoft Word document, it is not there:

It happened because I installed Open Office that replaced all the Microsoft Office shortcuts in this screen with Open Office icons. Then I uninstalled Open Office and the Microsoft Word shortcut was gone.
How do I add it to the Right Click > New menu list?
