Windows 10: Installed app not in Start Menu list

I had to totally rebuild my Windows 10 Pro Dell laptop. I downloaded and installed apps from the Microsoft Store and third parties, including Kindle. All my Store apps showed up in the Start Menu app list, as did all my third-party apps except for Kindle. What's haywire here, and how do I fix it?

Cannot hide app list in Start Menu Windows Home

Hi, suggestion in this thread on this topic here:
can not hide app list in start menu Solved - Windows 10 Forums

 

In Win 10 some apps are not listed in the Start Menu

Two of my most used programs are listed in the uninstall programs list, but do not appear in All Apps in the Start Menu, nor do they appear in the Most Used list in the Start Menu. Any suggestion how I can add them to my Start Menu, other than with tiles,
which I do not use?

 

Kill the letters! (Start menu apps list.)


One final hack/adjustment and I will be at peace.
So far no-one has come up with a way to remove the stupid letters from the start menu apps list... have they?

Please do NOT suggest third part apps.
I value the right click menu features on the Start button and all the third party Start Menu apps screw with this.
I don't want another program, I just want the stupid clumsy letters gone!

Any creative geniuses out there?
I'm not the only one who wants this, surely!





And it doesn't even work...
Is the name of the program used to determine where the app goes or the name of the company that makes the program.. or even whether it's free or not!
(See image F for Free!)
Useless and pathetic Microsoft!
