TL;DR Persistence can be achieved with Appx/UWP apps using the debugger options. This technique will not be visible by Autoruns. Two different approaches exists (registry keys).

Persistence using RunOnceEx – Hidden from Autoruns.exe
TL;DR - Found a technique to execute DLL files without being detected by autoruns.exe at logon. - Requires administrator rights and does not belong in userland. - Run this to Exploit: reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx\0001\Depend /v 1 /d "C:\temp\messageBox64.dll" RunOnceEx I finally had some time to do some unstructured research.
