How to restore security permissions to default settings?

Hello, I had problems sharing files on my network and I went to different support forums looking for answers. I changed user permissions on my (D/) drive and tried to add "Everyone" following instructions from other forum, I did something WRONG and I did not fix the problem and now I just create a new one because "SYSTEM" and "Authenticated Users" do not exist anymore. I need help to see if someone can tell me how to restore settings to default.

Thanks
