Function Kill-VM {
      <# .SYNOPSIS Kills a Virtual Machine. .DESCRIPTION Kills a virtual machine at the lowest level, use when Stop-VM fails. .PARAMETER VM The Virtual Machine to Kill. .PARAMETER KillType The type of kill operation to attempt. There are three types of VM kills that can be attempted: [soft, hard, force]. Users should always attempt 'soft' kills first, which will give the VMX process a chance to shutdown cleanly (like kill or kill -SIGTERM). If that does not work move to 'hard' kills which will shutdown the process immediately (like kill -9 or kill -SIGKILL). 'force' should be used as a last resort attempt to kill the VM. If all three fail then a reboot is required. .EXAMPLE PS C:\> Kill-VM -VM (Get-VM VM1) -KillType soft
  
      .EXAMPLE
         PS C:\> Get-VM VM* | Kill-VM
  
      .EXAMPLE
         PS C:\> Get-VM VM* | Kill-VM -KillType hard
