How put a shortcut on the desktop.

In All Programs (Press Windows key) > Find the program > Right click > select "more" > Select "Open file location" 

In this case you should end up in C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Lacerte (possibly a different drive on a network) - Find 2021 Lacerte Web Setup - Drag & Drop, i.e. Click and hold and drag the icon to your desktop and let go. 

Each season, drag the old one to the recycle bin and repeat for the new year. 

Unfortunately this does only work on the Windows desktop. If your desk is like mine there would be no room for it on the real desktop.
