I have a shortcut to a Steam game Age of Empires II Definitive Edition in my Misc folder, that sits on my desktop.
I've also told Indexing Options to index that folder:
So when I search for the game in the Start menu, it only finds Age of Empires II HD Edition, but not the Definitive edition:
The HD Edition shortcut has been in that folder for about a year, while Definitive Edition got placed there about a month ago.
Why can't Windows find the Definitive Edition shortcut?
