### Feature description
Everytime an update is beeing installed I face a new shortcut on my desktop. Since I like my desktop clean and doesn't understand at all why every program wants to place a shortcut there, I find it very annoying to have to delete it everytime again. Therefore I'd like to suggest to not create a shortcut if there was none before. Like that you can update it for people who want a shortcut and don't annoy people who like it clean.
