I already did that, and it didn't work.
They still start as background processes.

My startup tab only has the Realtek Audio Manager thingy, which I would keep.
Same for scheduled tasks, I only have the system tasks and my own stuffs.

Sometimes they appear in the task manager...

But they're not services.

I forgot to mention that I already tried these before,and obviously they didn't work. That's why I came here to ask.

Windows 10 starts apps automatically in the background, so when you start the apps, they will launch faster.
But I don't need that.

The background apps settings in the Settings app don't change...
