If I understand correctly  you want PowerShell to send the ENTER keystroke to some interactive application    wshell   New-Object -ComObject wscript shell   wshell AppActivate  title of the application window   Sleep 1  wshell SendKeys        If that interactive application is a PowerShell script  just use whatever is in the title bar of the PowerShell window as the argument to AppActivate  by default  the path to powershell exe   To avoid ambiguity  you can have your script retitle its own window by using the title  new window title  command   A few notes    The tilde     represents the ENTER keystroke  You can also use  ENTER   though they re not identical - that s the keypad s ENTER key  A complete list is available here  http   msdn microsoft com en-us library office aa202943 28v office 10 29 aspx  The reason for the Sleep 1 statement is to wait 1 second because it takes a moment for the window to activate  and if you invoke SendKeys immediately  it ll send the keys to the PowerShell window  or to nowhere  Be aware that this can be tripped up  if you type anything or click the mouse during the second that it s waiting  preventing to window you activate with AppActivate from being active  You can experiment with reducing the amount of time to find the minimum that s reliably sufficient on your system  Sleep accepts decimals  so you could try  5 for half a second   I find that on my 2 6 GHz Core i7 Win7 laptop  anything less than  8 seconds has a significant failure rate  I use 1 second to be safe  IMPORTANT WARNING  Be extra careful if you re using this method to send a password  because activating a different window between invoking AppActivate and invoking SendKeys will cause the password to be sent to that different window in plain text    Sometimes wscript shell s SendKeys method can be a little quirky  so if you run into problems  replace the fourth line above with this   Add-Type -AssemblyName System Windows Forms  System Windows Forms SendKeys   SendWait
