Make a powershell script with a .cmd (or .bat) extension

test.cmd

@powershell -noninteractive "& ([Scriptblock]::Create( ((gc -raw '%~df0') -replace '^@powershell.*' ) )) %*" & goto :eof 
###
### Example : Just use that first line in a .cmd file and it will execute this file with powershell!
###
param( $name, $lastname )

write-host -fore green "Well, hello $name $lastname"

<# Notes:
  this works just fine from cmd (or powershell) - even with named parameters: 

  C:\>test.cmd
  Well, hello

  C:\>test garrett serack
  Well, hello garrett serack

  C:\>test -lastname garrett -name serack
  Well, hello serack garrett

  ###
  Q: Why would you want to do this ?
  A: Because, a lot of people, don't run powershell as their shell, and running a .PS1 file from cmd doesn't run the script
