Basic menu in Windows 10

So i worked on my problem and I used PROCMON to look into it.

Explorer.exe go read Google Chrome.lnk (exemple here)

who is in c:\programdata\microsoft\windows\start menu\programs (menu démarrer/programmes in French)

As you can see, Google Chrome is installed on the computer BUT it didn't show in the Start Menu

And the list goes on with all the softwares, I only got the "modern apps" (or "basic apps") of Windows 10 in the Start Menu...

I installed all the Update (I'm currently at version 1709 of Windows 10) with no result or improvment...

I even installed Start10 menu to see what it will show... In the Windows 7 setting I can see my software but not in the Windows 10 setting (???)

So I can see and execute all my applications from there but keeping Start10 is not an option for us.

I tryed the Startmenu repair tool from Microsoft with no result.

In my search about this problem, I tryed the DISM, SFC, some Powershell command... and now, I'm lost... If someone got an idea, it would be welcome since we got some computers who show the same trouble...
