Powershell to close a running program gracefully without use's interact

[BetaTime]

I have this powershell code to close a program gracefully

 

Get-Process MyProgram | Foreach-Object { $_.CloseMainWindow() | Out-Null }

 

the problem is that it will pop-up a Windows asking user to hit 'OK' or to 'Cancel'! what powershell code I can force it selects OK and not prompts for user to interact? thanks.
