Right click on \Explorer and using the dialog menu choose New > Key and name it Shell Icons. Press Enter.

In the right pane of Shell Icons, right click on an empty area, and click/tap on New and String Value. Name it 29.
6. Modify String Value
Double click/tap on the 29 String Value to modify it. You should see a blank box called Value data.

8. Restart
You can now either reboot the computer or log off and on back again to complete the changes.
Afterwards, you should have a nice, clean desktop with no arrow shortcuts. Of course, you could go more advanced and define your own shortcut arrows or even change your system icons, but that is for another day.
For now, if you want a purer desktop with less clutter, just take the five minutes and make this registry change!
