Deploy using WOL and shut down only machines that were offline.

I think you can do this by looking at uptime.

1. Create a PowerShell step and make it Step 1.

   # https://blogs.technet.microsoft.com/heyscriptingguy/2013/03/27/powertip-get-the-last-boot-time-with-powershell/
   $Uptime_Raw = Get-WmiObject Win32_OperatingSystem
   $Uptime_Converted = $Uptime_Raw.ConvertToDateTime($Uptime_Raw.LastBootUpTime)
   $Uptime = ( Get-Date ) - ( Get-Date $Uptime_Converted )
   
   Write-Output "Uptime: $($Uptime.TotalHours) hours"
   
   if ( $Uptime.TotalHours -lt 1 ) {
   
       # Target was probably woken by WoL
       New-ItemProperty-Path "HKLM:\HARDWARE"-Name "Should I Turn Off"-PropertyType "String"-Value "Yes"-Force
   
   } else {
   
       # Target was probably not woken by WoL
       New-ItemProperty-Path "HKLM:\HARDWARE"-Name "Should I Turn Off"-PropertyType "String"-Value "No"-Force
   
   }

2. Create a Reboot step and make it the last step. Check for the box labeled "Shutdown Only". Set the Registry Condition like this:
   
   
   

Hi Colby, thanks for your solution, i'll give it a try. 

I have no experience in scripting and i have 2 questions. From what i see you use the LastBootUptime property to check last boot time and...

Question 1. do you write a new entry on the registry to check it on step 2?

Question 2. The condition is if boot time is less than 1 hour?

Thanks again.

1. Yes.
2. Yes.
