You can’t reliably do this. You could use a virus-like technique to hook into the Windows kernel, but your application is liable to be blocked by a virus scanner.
If you’re unhappy with users closing your application, why not remove local admin rights from your users and run your app as a Windows service? Windows will then stop them from closing your app.
