I'm developing Windows application. It is crypto-functioning notepad.

And its design(UI interface) is almost(approx 90%?) same with Microsoft Windows Notepad.

Differences are only some buttons and sub-windows for encryption and decryption.

I would like to distribute my program for non-commercial. In this case, can I use its UI interface legally?

    Microsoft probably encourages developers to maintain consistency in applications, so you shouldn’t have an issue. Years ago when I did some Apple S/W development, I read the Apple User Interface guidelines. I suggest that you find the equivalent Microsoft guidelines. – Mattman944 May 8 '20 at 8:49

  • Then, how can I fill in the copyright blank in the program details? I mean Can I use "All rights reserved" or "Some rights reserved" and sth like that? – 6991httam May 9 '20 at 3:05
  • "All rights reserved" is obsolete according to wikipedia: en.wikipedia.org/wiki/All_rights_reserved – Mattman944 May 9 '20 at 20:01
