PowerShell - Sendkeys
(How to send keyboard input with PowerShell to any open window or application)
In this video I demonstrate a practical use case for using sendkeys in a PowerShell script. You can use sendkeys to automatically click a button, or confirm a prompt for instance.
add-type -AssemblyName microsoft.VisualBasic
add-type -AssemblyName System.Windows.Forms
[Microsoft.VisualBasic.Interaction]::AppActivate()
[System.Windows.Forms.SendKeys]::SendWait()
