If you install spyder (or spyder3) with PIP (not Anaconda) you may have problem to lunch it from start menu.
There is a simple way to do that.
Right-click on the Spyder where is on
C:\Python37\Scripts
where Python37 is the location where you installed you python.
Then select “pin to start” from menu.
Now there remain only one things to do.
right click on the spyder icon on the start menu, and select
more->open file location
Right click on the spyder shortcut and choose
Property ->change Icon tab
Now you can choose a custom icon (I made it for you, dowload it here).
Also you can create a custome shortcut to lunch it.
