Windows 10: Untrusted remote access- NOW WHAT?

My PC has been compromised by untrusted remote access. Will a NEW PC and CHANGING EVERY PASSWORD on every account, get rid of them? How do I assure I don't unknowingly 'invite' them into my new PC?

Remote Access

1. Follow these steps to disallow remote access to your PC completely:
2. 1. Type “remote settings” into the Cortana search box. Select “Allow remote access to your computer”. This may seem counter-intuitive, but this opens the Control panel
   dialog for Remote System Properties.
3. 2. Check “Don't Allow Remote Connections” to this Computer. You've now disabled remote access to your computer.

Try these two steps and tell us if your issue gets solved. If it does not then your PC may be infected. Use a Good antivirus to remove the infection from your device completely.

hijacked via remote network access

Sounds like you are the recipient of stolen goods. All of our work laptops have this feature where it locks the BIOS and hard disk remotely if stolen, misplaced, or after a certain number of failed access attempts to the data on the disk without the TPM key.

I would suggest returning it to wherever you bought or got it.
