I think he considers notepad.exe one of the best applications expressly because it stops Windows from restarting when he doesn't want Windows restarted, which, ironically, it presumably wouldn't do it if had Notepad++'s better-designed and usually preferable behavior. (The Notepad+Windows case seems like botches (individually user-hostile forced reboots and poor handling of state on restart for Windows and Notepad respectively) partially cancelling each other out.)
