NetDDE.exe (Microsoft) Microsoft Windows Network DDE server (DDE = Dynamic Data Exchange). Network DDE is a technology that allows applications that use the DDE transport to transparently exchange data over a network. For the layman a typical application of NetDDE is chatting over a network where WinChat, or some other chat program, will automatically be started by NetDDE when someone else on the network calls you. In this particular example, without NetDDE running in the background you would have to be running WinChat at all times in order to instantly receive a chat message. Recommendation : If NetDDE is running on your PC it was probably configured in this manner by some software that needs it to "do things" over a network, like the WinChat chat program mentioned above, or Microsoftâs Hearts networked game for that matter. If you do not have such software running on your PC, or do not use it, then simply disable or delete NetDDE with Startup Manager.
