Hello,

I am trying to figure out how to create a script (PowerShell or Bash) to send a message to multiple computers for the user to reboot at there earliest convenience to install updates. I would like a popup to stay on there desktop until they acknowledge it. I will be sending to multiple computers so if it could reference a text doc with the list of computers that would be great. I will open a Command Prompt or PowerShell with my admin account and run the script. All computers are Windows 10. Thank you for any help you can provide.

Windows Server PowerShell
Windows Server PowerShell
Windows Server: A family of Microsoft server operating systems that support enterprise-level management, data storage, applications, and communications.PowerShell: A family of Microsoft task automation and configuration management frameworks consisting of a command-line shell and associated scripting language.

    Hi,

    You can try something like below 

    $file = 'C:\tmp\com.txt'  
$message = "Computer will be rebooted."  
Get-Content -Path $file | ForEach-Object {  
        msg * /server:$_ $message  
    }

    Best Regards,
    Ian Xue
