For students learning, if we can not afford the license of WinEdt, we can try to change the exit setting.

Solution

Add the following codes in Options—->Options Interface—->Advanced Configuration—->Event Handlers—->Exit before end.

RegDeleteValue('HKEY_CURRENT_USER', 'Software\WinEdt 10', 'Inst');
DeleteFile('%B\WinEdt.skd');

ReadFile('%b\WinEdt.dnt',1,0,0,0);
ReplaceInString( "%!1", "1089357896855742345", 4, 23, 0, 2 );
WriteFile( "%b\WinEdt.dnt", "%!2", 0, 0, 0, "" );
