I want to set up a task scheduler to run a PowerShell script every 1 hour with no prompt windows pop-up.

Here is the command I tried:

schtasks /create /sc hourly /tn $Task-Name /st $ScheduleTime ` /tr "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -windowstyle hidden -NoLogo -NonInteractive -NoProfile -ExecutionPolicy Bypass -command C:\MyScript.ps1" `

I added all parameters I found.

-windowstyle hidden -NoLogo -NonInteractive -NoProfile

The script runs in the background with no problem but it still at the beginning pops up for a second before hides itself.

Does anyone know how to make a task scheduler to run the ps1 script fully hide with no pop-up windows?

    To run a command script and hide the window from appearing, call the task using VBScript.Run. Commented Apr 8, 2021 at 10:28
  • @JosefZ I refer to your link and solve the issue by the VBS. Thank you so much! Could you please post the answer below? Then I can accept the answer. Commented Apr 8, 2021 at 23:57

I am achieving this via the task scheduler, i have set the action value to start a powershell program with the following arguments:

-executionpolicy bypass -noninteractive -file "C:\PathToYourScript"

enter image description here

the key argument here is -noninteractive, it does not present an interactive prompt to the user.

Thank you, JosefZ for solution!

Here is an example of VBS script.

' run_hidden.vbs Set objShell = CreateObject("WScript.Shell") objShell.Run "powershell.exe -ExecutionPolicy Bypass -File ""C:\path\to\script.ps1""", 0, False

create script and add it to Start Program action.

  • program: wscript.exe
  • argument: "C:\path\to\run_hidden.vbs"
