Final answer:
The Microsoft Edge icon might reappear on the desktop due to update settings or system maintenance that creates a shortcut to remind or encourage users to use Edge. To stop this, delete the existing shortcut and check the browser settings or Task Scheduler for related tasks.
Step-by-step explanation:
The Microsoft Edge icon may keep appearing on the desktop due to a setting called 'Create a desktop shortcut' which could be enabled during updates or installations, or as a result of certain system maintenance tasks that Windows periodically runs. When Microsoft Edge updates, the system might be programmed to remind the user about Edge by placing its shortcut on the desktop. Additionally, some users may accidentally create multiple shortcuts without realizing it.
To prevent the icon from reappearing, right-click on the Microsoft Edge shortcut on the desktop and delete it. If the icon continues to show up, check the Edge browser settings or Task Scheduler to see if there are any tasks that create a shortcut after updates.
