DDE is "Dynamic-Data Exchange," a method of inter-process communication that dates back to Windows 3.0.

One of the few places where it's still used is to add items to the start menu during installation. Installers used to talk to Program Manager via DDE to create program groups and icons, now they do the same, but with Explorer.

It was also used to open a document in an application that's already running (otherwise the command line is used), but I don't know where else. (I didn't do any Windows programming back then.)
