Set Node.exe to use cmd.exe and not powersehll.exe

When running node command it's automatically using powershell.exe and not cmd.exe. The "comspec" settings are set to cmd.exe, there is any other place where I should change this?

Node v6.10.2, Windows 8.1 pro

If someone know Salesforce DX, this is what I'm running, the sfdx is using node and node.exe trigger powershell.exe and not cmd.exe:

sfdx force:auth:web:login --setdefaultdevhubusername --setalias "dev-hub-org"
