For me, in Windows 10, I can type "calc" into the search menu and it will recommend and open the calendar app instead of the calculator app 2 out of 5 times.
I will search for an app that I have installed and instead of opening the app it will open a bing search for the app that I have installed.
It's so infuriating that if there were a M$ rep within arm reach I might be tempted to do violence towards them.
