Hello,
Thank you for posting in Q&A forum.
Yes, the Dynamic Data Exchange (DDE) communication protocol is supported in Windows 11. DDE is a set of messages and guidelines that allows applications to share data and communicate with each other. This protocol has been a part of Windows for many years and continues to be supported in the latest versions, including Windows 11.
I hope the information above is helpful.
Best Regards,
Yanhong Liu
