  You can use Get-VM and Stop VM to perform the actions.

  (See example 2) http://technet.microsoft.com/en-us/library/hh848479.aspx

  http://technet.microsoft.com/en-us/library/hh848468.aspx

  Also, the Start-Sleep cmdlet: http://technet.microsoft.com/en-us/library/ee177002.aspx

  You can use the Get-VM to find your VMs then pass those into a foreach loop which would stop each one then wait for 1 minute before processing the next.

  Hi Alex 

  Im done with that part but I need a foreach loop that will set the condition to loop through the VM and shut them down per minute and end up shutting down the host. 

  
  $VM = Get-VM -ComputerName Server1 
  $VMR = $VM | Where-Object {$_.State -eq 'Running'}

  Can you try something like this :

  
  

  $VM = Get-VM -ComputerName Server1
  $VMR = $VM | Where-Object -FilterScript {
    $_.State -eq 'Running'
  }
  ForEach ($Machine in $VMR)
  {
    Stop-VM $Machine
    Start-Sleep -Seconds 60
  }
  Stop-Computer -ComputerName Server1 -Force

  Thanks a lot Tim so what happens if I've got multiple VM Host and I would like to run the script on all the VM host.

  It's pretty much the same.  Here's an example.
  
  $servers = @('server1', 'server2', 'server3')
  ForEach ($server in $servers)
  {
    $VM = Get-VM -ComputerName $server
    $VMR = $VM | Where-Object -FilterScript {
      $_.State -eq 'Running'
    }
    ForEach ($Machine in $VMR)
    {
      Stop-VM $Machine
      Start-Sleep -Seconds 60
    }

  Stop-Computer -ComputerName $server -Force

  }

  That looks ok, but you can make it a bit cleaner, the filter command is a bit dated now:

  $servers = @('server1', 'server2', 'server3')
   ForEach ($server in $servers) 
   {
     $VMs = Get-VM -ComputerName $server| Where-Object {$_.State –eq 'Running'}
     ForEach ($Machine in $VMs)
     {
       Stop-VM $Machine
       Start-Sleep -Seconds 60
     }
  
  Stop-Computer -ComputerName $server -Force
  }
  
  

  
  A further improvement would be to run each one of the servers in parallel or remotely execute the code on the servers themselves. For one or two servers it doesn't make a huge difference but if you've got 10 servers each with 4 VMs then you're looking at a run time of 40 minutes instead of a run time of 4.

  Get-Vm -computer $comp | Stop-Vm
  Stop-Computer $comp

  Accomplishes the same thing as Stop-Vm does nothing on a stopped VM and the pipeline waits until the machine is stopped before moving on.

  THere is no need to be more complicated then that.

  If you have a lot of VM then the shutdown can take a long time doding it this way.  Using a parrallel workflow would be much faster.

  Bit dated?  Disagree on that one. 

  -FilterScript is what Where-Object actually uses when you omit the parameter name.
  Best practices state that full parameters should be used for commands, which is what that is.

  Hi Everyone 
  
  Just a quick question if want to convert the script to start up the the VM Host plus the VM's is the below correct.
  
  $servers = @('server1', 'server2', 'server3')
   ForEach ($server in $servers) 
   {
     $VMs = Get-VM -ComputerName $server| Where-Object {$_.State –eq 'Off'}
     ForEach ($Machine in $VMs)
     {
       Start-VM $Machine
       Start-Sleep -Seconds 60
     }
  
  Start-Computer -ComputerName $server -Force
