C++ can encrypt the file when it creates it, but it doesn't ride along with it to decrypt it for readers.
For that you would have to assign a specific file type (filename extension) to a new C++ application, supply that application to the reader, and register the extension with Windows on the machine using the file with that extension.
Hope that helps.

That has nothing to do with the file, it would be done in the operating system, and Windows can't do it.
