Hello,

Welcome to Microsoft Q&A!

How to differentiate the clipboard content changed form our app or from another app in UWP ?

Just talk from the UWP side, there is no UWP Api could achieve what you want. The Clipboard.ContentChanged Event tracks the changes of the data stored in the Clipboard from the system but it won't know the source of the clip data.

If this feature is very important, you submit a feature request about this feature in the Feedback Hub. You could find the Feedback Hub in the Start Menu. Please select Developer Platform->API Feedback as the category when you submit your request. The related team will check the request.

Thank you.
