What is DDE Server Window? Simple explanation.

If you visit my blog, you will most likely encounter DDE server windows explore.exe application error. Today I will briefly and clearly explain what DDE Server Window is and how to remove the error.

Short answer

It is an old Windows technology that allows applications to communicate with each other by exchanging data. This is not a third-party program or virus.

What is Windows DDE Server?

Windows DDE server means – Windows Dynamic Data Exchange server. Windows offers several ways to transfer data between programs. One option is the Dynamic Data Exchange protocol (DDE). 

The DDE protocol is a collection of messages and guidelines. It uses shared memory to send messages between applications that share data. The DDE protocol can be used by applications for both one-time data transfers or continuous data exchanges, in which applications send each other updates as new data becomes available.

It is an extremely primitive version of OLE (Object Linking and Embedding), allowing you to insert Excel spreadsheets into a Word Document.
