Autorun currently only controls Win32 Applications and the WinRT Subsystem controls Universal Apps (formally known as MUI or Metro Apps)
Ok, that helps me a lot. Thank you.
My only way to get rid of Skype(32bit) is then to uninstall it, and use the x64 version (desktop one)? That sucks. I can't uninstall all my apps just to prevent them from autostart. What would be the point of having the MUI interface then ?
Could it be the consequence of some apps connected to onedrive. It will explain why my Metro OneNote always starts by itself as a background process, even if my desktop OneNote is turned off.
When the SP3 connects to a network, it syncs to onedrive automatically (which is the behavior I want). So maybe some apps are connected my onedrive account and would automatically start to sync and run in background ? It would be a good reason to explain why they keep turning on even if I kill them.
