Command Prompt Here was a mandatory install, forgot all about it!

It's a simple enough registry edit that I've memorised it and apply it to all the machines (including VMs) I work with.

    HKCU\*\shell\Command Prompt Here\command = %WINDIR%\system32\cmd.exe

On modern Windows it's built in, you just hold ctrl+shift (actually I think just shift will do) as you right click.

I think you can also click on the address bar in Explorer, and type "cmd" or "powershell". Even "bash" if you install WSL.

With Alt+D to focus the address bar, this is super convenient. I use it all the time.

Command Prompt Here is also directly in the File menu of Windows 10's File Explorer's ribbon. Alt+F,R is the shortcut.

(File Explorer's ribbon follows your Win+X setting that if you have PowerShell your default, that shows up instead of classic Command Prompt.)

That's not as convenient as being able to do it without syncing with the keyboard and with anything selected --- if you do it on a file, it will open in the directory the file is in.
