The shortcut created by the installer is named "Downlord'sFafClient" by default. And changing it in the installer only changes the name of the folder it is put in. The only way is to edit it manually. Which I do, and rename it to "Downlord's FAF Client" cause Windows search has a hard time with it being all one word.
I copied your suggestion to Github: https://github.com/FAForever/downlords-faf-client/issues/1939
Well no sure how to rename
