On Windows, you Right click My Computer→Properties→Advanced system settings (on the left pane). Go down to the bottom and select Environment Variables.... Change the ComSpec to whatever shell application you want.
The default value is %SystemRoot%\system32\cmd.exe.
For PowerShell it is %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe.
