PS C:\orchestrator\AddServerRolesAndFeatures> powershell -ExecutionPolicy ByPass -File C:\orchestrator\AddServerRolesAndFeatures\InstallRolesAndFeatures.ps1 \quiet
Your OS version is:Windows Server 2016 Datacenter
Computername (Press Enter for current computer - ABCHOSTNAME):

If the script requires an enter, you should post the script, not how you invoke it. — vrdse

Thanks for the response !!! Yes, the script requires enter. I cannot change the script , I am sharing you the snippet of it.. — gary

If you are going to post code. Post the actual code. Not a screen shot. Makes it easier for people to help you. I don't see why you can't change the script. — Matt

"I cannot change the script" - yes you can. Make a copy and remove the requirement for the Enter keystroke. If it was intended to be automated, it should not require user interaction. — Bill_Stewart

The running script has read-host in it which requires input by design. There are not really any pretty ways around it short of using sendkeys or third party apps like AutoHotKey. Only thing I could think is to surpress Read-Host by running PowerShell in non-interactive mode which

Does not present an interactive prompt to the user.

That has a side effect where an error will be triggered. Consider the following script.

$var = "Original"
$result = read-host -Prompt "Push Enter or type and such"
if($result){$var=$result}
$var

Set a variable to a string value and prompt the user to change it. Display the results whether the user enters null or nothing.

Now run that in noninteractive mode...

PS D:\Temp\PSH> powershell.exe -Noninteractive -file .\skipReadHost.ps1
powershell.exe : read-host : Windows PowerShell is in NonInteractive mode. Read and Prompt 
At line:1 char:1
+ powershell.exe -Noninteractive -file .\skipReadHost.ps1
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (read-host : Win...ead and Prompt :String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

functionality is not available.
At D:\Temp\PSH\skipReadHost.ps1:2 char:11
+ $result = read-host -Prompt "Push Enter or type and such"
+           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Read-Host], PSInvalidOperationException
    + FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.ReadHostCommand

Original

Notice at the end the string came out with its first state. This all depends on how the script handles this prompt being skipped.

From the looks of it you could also just remove the read-host logic from the script and avoid this issue altogether.

Run it like that:

powershell {$wshell = New-Object -ComObject wscript.shell; $wshell.SendKeys('~'); powershell -File "C:\orchestrator\AddServerRolesAndFeatures\InstallRolesAndFeatures.ps1"}

Explanation:
In order to send enter key stroke you can do it by this code:

$wshell = New-Object -ComObject wscript.shell
$wshell.SendKeys('~')

In the solution I send the enter keystroke before you run the script and then it will receive it and continue.
