After installing the app in Windows, you'll get 4 desktop shortcuts for Google Drive and 3 of its web apps (Google Docs, Google Sheets, Google Slides). Google's mostly silent installer doesn't ask if you want these shortcuts. I think it's impolite to clutter people's desktops with 4 shortcuts without even asking if it's OK.
The same shortcuts are also added to the start menu / screen:
The shortcuts for Docs/Sheets/Slides let you create new documents/spreadsheets/presentations from your browser. Chrome users can already install apps and add shortcuts to the new tab page or the app launcher. Sure, you can easily delete the shortcuts, but you shouldn't have to do that.
