I know you can drag the MSFS Icon to the desktop, however it ends up being a purple square with the MSFS logo so tiny you can barely see it.
Can we get a proper old school icon please?
You can create your own icon files if you wish, and use that instead. You can also change their size. The MSFS one doesn’t seem to change when you change your desktop icon size.
Desktop icons all have the same size, if you can barely see the Flight Sim icon you will not find the drive or paper bin icons either 
but here are some different icons:
But these will have the same size as the actual Flight Sim 20 icon after changing it, try setting the desktop scaling to 125 or 150% first.
You can go into your display settings and in Desktop settings, choose the Large Icon option. That simple.
