In windows, whenever I install LibreOffice as an update on an already-existing installation, it will delete the previous shortcuts and start menu entries that were there, thereby also deleting the pinned files and file opening history for LO applications, and forcing to re-pin the icons to the task manager. Would be better if it would work like a regular update in other software, which does delete such info.
