  • Gracefully close all windows of an application

    This command will loop until the process no longer exists, calling closemainwindow() this is as if the user clicked the close window x in the upper right hand corner and gives the user an opportunity to save work in many applications like notepad and other things. The $'s are escaped for Cygwin, if you want to run the same command from the RUN box or cmd.exe shell then just unescape the $'s: powershell -Command "while ($true){Try{$process=Get-Process calc -ErrorAction Stop}Catch [Microsoft.PowerShell.Commands.ProcessCommandException]{break;}if ($process) {$whateva=$process.CloseMainWindow()}else {break;}Start-Sleep -m 500}" Show Sample Output
