How to remove MDM policies when I don't even have any MDM listed?

Access work or school Windows is empty, I have nothing to disconnect.

Provisioning packages is also empty, nothing to do there.

And I have no Microsoft account.

I tried removing them via regedit, but they keep coming back and yet I have tens of random policies that includes: random updates without any notice and probably other malicious garbage, how do I get rid of them?

If you disable MDM enrollment it should solve your issue. In order to do that you have to be an Administrator on the machine.

Using the GP editor, the path is Computer configuration > Administrative Templates > Windows Components > MDM > Disable MDM Enrollment.

You can find the registry key here:

\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\MDM

Set DisableRegistration to 0
