Find the original name of the message received using the RegisterWindowMessage API

Question

When debugging an application in an attempt to improve performance, I found that it wastes time processing a message that is greater than 0xC000. This is obviously a post created by the API RegisterWindowMessage. However, the application uses more than two hundred such messages; Is there a way to find the original name of the message by its numerical value?

There is no official API to get the name of a registered window message.

RegisterWindowMessage() RegisterClipboardFormat() ( API), Windows GetClipboardFormatName(), .
