Deploy login popup window/message to batch of computers on network?

Question

Is there a third-party Windows 7/8/10 software solution where I can deploy messages/notes to a list of computers on my network after I work on them? I'm in IT and sometimes when we do department-wide modifications to machines, we get e-mails asking "Why did you touch my computer? What did you do? I saw you logged in!" etc.

I'd like to be able to remotely send batch notices that detail the modifications we made to their computers. I'd like the message to pop up in a window (that appears only once on login, then never again) that they can then close.

(We do already manage most of our computers on our network using LANDESK, so if someone has a clear & easy solution through that, that might work too.)

From here: https://stackoverflow.com/a/29017619/704977

PowerShell allows you to remotely notify users:

$PCLIST = Get-Content 'C:\TEST\PCLIST.TXT'

ForEach ($computer in $PCLIST) {

    Invoke-Command -ComputerName $computer -Scriptblock {
        $GetUserName = [Environment]::UserName
        $CmdMessage = {C:\windows\system32\msg.exe * 'Hello' $GetUserName 'This is a test!'}

        $CmdMessage | Invoke-Expression
    }

}

You could use either the computer names in a text file like the above code does, or you could simply replace the $computer after Invoke-Command with a specific computer name.

This will likely require administrative privileges on the remote computer.
