Search doesn't find executables that are idexed

Hello
Usually when you hit start and begin typing the name of the program you want to start, it shows up right away, right?
I have a clean install of windows 10 on my C: drive and programs on the F: drive that are from when I used w7 (not ok i know but if a program stops working I'll just reinstall it), but when I search for Steam for example, it won't show up even if that folder is in the index and I even added steam to the start menu, so when I click start I can see steam there but it won't find it if I begin typing S-T-E.. you get the idea. Is there any way of including all programs in the search function or do I have to reinstall every program? This problem applies for every program that are on the F: drive and it seems unnecessary to add every program to the start menu just to be able to access them quickly, you know.

Answers are appreciated!

I'm having this exact same problem. In Windows 7 I was able to type any file, including executable names, into the start menu search and they were shown. With Windows 10 that just doesn't happen.
