Hi,
Strange, Settings > Personalization > Start ::

I can disable "Show most used apps" and "Show recently opened apps" using this key:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"Start_TrackDocs"=dword:00000000
"Start_TrackProgs"=dword:00000000

But I also need to disable "Show recently added apps" via registry and I couldn't find the related key.
Anyone can help, please?!
Thanks
