How to change CMD start directory [duplicate]
If you hit the Win (Start) button and type CMD search field, instead of clicking Command Prompt (cmd.exe or Command Prompt depending on Windows version), either right click and choose properties, or if not present, choose Open File Location then right click and choose properties of the CommandPrompt shortcut.
You can get to it directly in this folder: %APPDATA%\Microsoft\Windows\Start Menu\Programs\System Tools
In the "Start in:" field, it normally says %HOMEDRIVE%%HOMEPATH%
This makes cmd start in the home folder. You can change this to be whatever you'd prefer.
