Windows 10: command prompt in S mode

I cannot find command prompt or Powershell ANYWHERE on my new laptop. I get an error message about the app not being safe due to S mode on my computer. Anyone know how to run a command in S mode? Surely there's a way around this! The whole reason I need this is because I think I have a pre-used laptop that's been sold as new and we're trying to diagnose. Thx

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?

 

command prompt will not open in safe mode with command prompt

I am repairing a laptop for a friend and I need to access windows in safe mode and the owner has forgotten the password to the main user. I tried logging on with the administrator profile in safe mode but it is not showing up so I was going to use command prompt in safe mode with command prompt but command prompt will not open when I boot that option. Does anyone have any hints for me to figure this out?

Command prompt is only accessible from the Administrative Profile, this is to prevent general users from accessing and bypassing controls.
One method is to remove the drive and connect it to another system.
