There are many times a Sysadmin might want to do this without using RDP or similar tools, and I recently remembered winrs is built into all modern Windows systems and allows one to do just that!
So open an elevated command windows on a local PC and run winrs -r:remotepc-name-or-ip cmd
This then opens a command shell on the local PC. Use 'exit' when you have finished.
Use winrs /? for a full list of help and syntax.
No third party software to install - just works!
