Steps to reproduce

In Windows Run dialog type this:
PowerShell.exe -WindowStyle Hidden -Command ping www.microsoft.com

Expected behavior

There should be no window, right now you can't start powershell without window flashing, making it rather useless e.g. for scheduled tasks.

Note I think this is intended behavior, but it's confusing and new option is probably required. If you search how to run a powershell in scheduled task, the go-to workaround is to do a vbs script of all things! Such as:

Dim shell,command
command = "powershell.exe -nologo -File D:\myscript.ps1"
Set shell = CreateObject("WScript.Shell")
shell.Run command,0

This is not a good thing, powershell needs this feature in the shell itself, scheduled tasks are important feature and having a window flash on scheduled task is a really bad experience.

Actual behavior

It flashes the powershell window briefly.
