Windows 10: Windows power shell black screen and cmd not working

I bought a pc from my friend and i created my account but we forgot to delete his account and make my account to system administrator. Until now i'm not used cmd but needed to my new job.

I try to run cmd but it's not worked then i used windows power shell and it's worked but not everything.

So i deleted my friend account who was the system administrator and now i'm the system administrator but when running windows power shell i always got a black screen and cmd still don't working.

Somehow can fix this ? I need this pc to work. Windows 10 64bit and not authenticated yet.

The tutorials provided are just a list of troubleshooting steps. Use only the steps which apply to you.

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.
