"Preparing Windows" hangs to black screen

On a 1511 build.

What could be the cause of this? I can go to task manager, run cmd prompt and everything, just desktop wont show up.

Most probably a Post-setup command that is not automated, has a prompt which cannot be shown at that stage.

Was there a post-setup command added, need any help?

Here is how to debug it, in my reply.

Sadly its something in the component removal on 1511.

Can't pinpoint what it is, i applied the same profile as i used on 1607 is when i first discovered it. After that ive been trying to strip from a manual clean point but no luck so far.

I'll keep trying.

Edit: might be one of the core metro services i deleted, I'd expect it to break most 'app' stuff but not the entire windows login process. Altho every Windows 10 build is different nowadays. We'll see.
