Donc, cette réponse implique le téléchargement d'un script gratuit LINQPad pour exécuter le script puis l'exécuter.
exécutez-le et il vous demandera de placer votre curseur sur la fenêtre que vous souhaitez fermer. Il interroge cette fenêtre pour le titre, vous le montre, puis vous demande si vous souhaitez le fermer.
// close an app's foremost window - will try to just close whatever window the mouse is over first, see if that does the trick
// close works when linqpad runs as administrator. Used to close a modal in linqpad that was stuck
