"New Word Document" missing from right-click context menu?

When I right-click on an empty area of the desktop, I get a full context menu. Hovering over "New" brings up a new sub-context menu. "New Word Document" suddenly disappeared – it always used to be there!

So how can I put it back? This is on a Windows 7 system.

Base on similar questions I checked, this might solve the issue:

Click Start > Run > and type winword.exe /r

If this solution didn't work, you can have a look at How can I add an item to the 'new' context menu?

My situation was that I had both Office 2007 and Office 2010 installed on the same machine, via the drive image deployed to my work PC. Having both versions caused control struggles, with each version vying for control each time I launched it, so I opted to remove 2007. In so doing, the right-click "Create new" options disappeared.

I solved this by going to Control Panel → Programs and Features → Microsoft Office → Change → Repair.
